Validating Credit Cards Credit card numbers are not randomly chosen. There are rules that determine which credit card numbers are valid. This is a limited attempt to prevent fraud. If you just make up some number, it is unlikely to be valid. You are going to write a program to determine if a number is a valid credit card number. A credit card number must have between 13 and 16 digits. The first digit or two deter mines what type of card it is: Begins with Card Type Visa MasterCard 37 American Express Discover For our purposes, a number that doesn\'t begin with one of these sequences is not a valid credit card number. The algorithm for validating credit cards is credited to Hans Luhn of IBM. To illustrate the algorithm, we will use the sample number 4388576018402626. First, we see that this must be a Visa card, since it starts with 4. To validate it 1. Double every second digit from right to left. If doubling of a digit results in a two- digit number, add up the two digits to get a single-digit number. 2 2 4 2 2 4 2 38 1 2 12 2 3) 5 2 8 2 16 (1 6-7) 4 2 2. Now, add all the single digit numbers from the previous step. 4 4 8 2 3 1 7 8 37 3. Add all the digits in the odd places from right to left in the number. 6 6 0 8 0 7 8 3 38 4. Add these two values together. 37 38 75 Solution #include #include #include int main(void) { double cardnumber; printf(\"Give me a number: \ \"); scanf(\"%lf\", &cardnumber); if(cardnumber < 1000000000000 || cardnumber > 10000000000000000) { printf(\"INVALID\ \"); return 0; } if(cardnumber < 100000000000000 && cardnumber > 9999999999999) { printf(\"INVALID\ \"); return 0; } char creditcard[17]; sprintf(creditcard, \"%f\", cardnumber); char* ptr_cc; ptr_cc = strtok(creditcard,\".\"); int card_size = strlen(ptr_cc); int sum = 0; for(int i = 1; i < card_size; i+=2) { int x = creditcard[card_size-1-i] - \'0\'; int prod = 2 * x; if(prod>=10) { prod = prod%10 + prod/prod%10; } sum += prod; } for(int i = 0; i < card_size; i+=2) { int x = creditcard[card_size-1-i] - \'0\'; sum += x; } if(sum%10 != 0) { printf(\"INVALID\ \"); return 0; } else if(creditcard[0] == \'4\') { printf(\"VISA\ \"); return 0; } else if(creditcard[0] == \'3\' && (creditcard[1] == \'7\' || creditcard[1] ==\'4\')) { printf(\"AMEX\ \"); return 0; } else if(creditcard[0] == \'5\' && (creditcard[1] >=\'1\' && creditcard[1] <=\'5\')) { printf(\"MASTERCARD\ \"); return 0; } else { printf(\"INVALID\ \"); return 0; } }.

Use Gauss\'s approach to find the following sum (do not use formulas): 8 + 14 + 20 + 26+ ... + 86. The sum of the sequence is . Solution The sequence given is: 8+14+20+............+86 Now to calculate the sum of this sequence using Gauss approach we use the following steps: Now, 8+86=94;14+80=94;20+74=94 and so on..(basically we are trying to show that the sum of extreme terms.ie.the sum of 1st and last term,2nd and the second last term and so on, are the same in a sequence with common difference) Now,we have to find the number of terms in the sequence. 8=8+0*6 (We are using 6 here as the common difference between the terms of the sequence is 6) 14=8+1*6 20=8+2*6............ 86=8+13*6 Hence,the no of terms(n) is 14......Therefore no of pairs is : n/2=14/2=7....This indicates that we have 7 pairs of numbers whose sum is 94. The sum of the sequence is= 94*7=658.

Use the definition of the Laplace transform to find L{f(t)} f(t) = {t, 0 ? t ? {2 Solution Definition - Laplace transform of a function f(t) is defined as follows L{f(t)} = integrate[0, inf] f(t)e-st dt So for 0 t 1, the questions says f(t) = t and you just plug it into the definition and get integrate[0, inf]{te-st}dt and evaluate the integral. First step of the intgral is integration by parts, let u=t and dv/dx = e-st , then integration by part formula says uv - integrate v(du/dx), which gives us [- (1/s) te-st] - integrate[0, inf] {-(1/s)e-st}dt. Note that the \"uv\" part [-(1/s) te-st] is equal to zero, and then you just have to integrate by parts the integral part again to get 1/s2 same thing for t 1 . plug in 2-t, and you get L{f(t)}=integrate[0, inf]{(2-t)e-stdt. Notice that the -t term you already did it in part a so you really just have to integrate 2e-st . which gives you 2/s.

Matlab question: Discrete Fourier Transform (DFT) and Fast Fourier Transform (FFT) The DFT of a sequence x(n) with length N is defined: X[k] = sigma_n = 0^N - 1 x[x] W^kn for each k = 0, 1, ..., N - 1. Where W = e^-j(2 pi/N) The inverse DFT is given by: X[n] = 1/N sigma_n = 0^N - 1 x[k] W^-kn for each n = 0, 1, ..., N - 1. The Fast Fourier transform (FFT) is an efficient algorithm to compute the DFT Use \'fft\' function to calculate the Fourier Transform of a sequence, x = [1, 2, 3, 4, 5, 6, 7, 8] Use \'ifft\' function to calculate the inverse Fourier Transform of the result you get in (a). Re-do (a) and (b) using your own DFT and inverse DFT functions. Solution In mathematics, the discrete Fourier remodel (DFT) converts a finite collection of equally-spaced samples of a feature into an equal-period series of similarly-spaced samples of the discrete-time Fourier remodel (DTFT), which is a complex-valued feature of frequency. The c language at which the DTFT is sampled is the reciprocal of the duration of the input collection. An inverse DFT is a Fourier collection, the usage of the DTFT samples as coefficients of complicated sinusoids on the corresponding DTFT frequencies. It has the equal pattern-values as the original enter sequence. The DFT is therefore stated to be a frequency domain illustration of the original input collection. If the authentic series spans all the non-0 values of a feature, its DTFT is non- stop (and periodic), and the DFT gives discrete samples of one cycle. If the authentic sequence is one cycle of a periodic feature, the DFT affords all the non-0 values of 1 DTFT cycle. The DFT is the most essential discrete transform, used to carry out Fourier analysis in many sensible packages.[1] In virtual sign processing, the function is any quantity or sign that varies through the years, which includes the strain of a legitimate wave, a radio signal, or day by day temperature readings, sampled over a finite time c program languageperiod (regularly described by way of a window characteristic[2]). In image processing, the samples can be the values of pixels alongside a row or column of a raster photograph. The DFT is likewise used to correctly resolve partial differential equations, and to perform other operations which include convolutions or multiplying big integers. because it deals with a finite amount of records, it could be applied in computers through numerical algorithms or maybe devoted hardware. these implementations usually appoint green speedy Fourier rework (FFT) algorithms;[3] a lot so that the phrases \"FFT\" and \"DFT\" are regularly used interchangeably. prior to its present day usage, the \"FFT\" initialism may have also been used for the ambiguous term \"finite Fourier rework\".

2. Let J R R be Thomae\'s function and let g:R R be the sign function ie. if a 0 g(z) if a 0 -1 if a Solution Z 1 0 f dx = 0. To show this, let P = {I1, I2, . . . , In} be a partition of [0, 1]. Then, since f(x) = 0 for x > 0, Mk = sup Ik f = 0, mk = inf Ik f = 0 for k = 2, . . . , n. The first interval in the partition is I1 = [0, x1], where 0 < x1 1, and M1 = 1, m1 = 0, since f(0) = 1 and f(x) = 0 for 0 < x x1. It follows that U(f; P) = x1, L(f; P) = 0. Thus, L(f) = 0 and U(f) = inf{x1 : 0 < x1 1} = 0, so U(f) = L(f) = 0 are equal, and the integral of f is 0. In this example, the infimum of the upper Riemann sums is not attained and U(f; P) > U(f) for every partition P. A similar argument shows that a function f : [a, b] R that is zero except at finitely many points in [a, b] is Riemann integrable with integral 0..

In aqueous solution, Cd2+will precipitate out of solution in the form of CdS in the presence of hydrogen sulfide (H2S). The Ksp of CdS = 1.0 x 10-28 and Ksp of H2S = 1.0 x 10-26 for the reaction: H2S (aq) = 2 H+(aq) + S2-(aq) a. Write the balanced net ionic equation for the reaction of cadmium ion with hydrogen sulfide to form cadmium sulfide solid. b. Write the equilibrium expression for the equation in part a. c. Calculate Koverall for the reaction in part a. d. Calculate the [Cd2+] in a solution saturated with H2S (0.10 M) at a pH = 2.00 ([H+] = 0.010 M). Solution a) The balanced ionic equation for the formation of cadmium sulfide from cadmium ion and hydrogen sulfide is given as Cd2+ (aq) + H2S (aq) <=======> CdS (s) + 2 H+ (aq) ……..(1) b) The equilibrium constant for the reaction is given as Koverall = [H+]2/[Cd2+][H2S] (ans) Note that the concentration of a solid is not written in the expression for the equilibrium constant. c) Write down the two ionization reactions as below. CdS (s) <=======> Cd2+ (aq) + S2- (aq) ……..(2) Ksp = [Cd2+][S2-] H2S (aq) <=======> 2 H+ (aq) + S2- (aq) …….(3) Ka = [H+]2[S2-]/[H2S] Subtract (2) from (3) and obtain Cd2+ (aq) + H2S (aq) <======> CdS (s) + 2 H+ (aq) Koverall = [H+]2/[Cd2+][H2S] = ([H+]2/[H2S])*(1/[Cd2+]) = ([H+]2[S2-]/[H2S])*1/([Cd2+][S2-] = Ka*1/Ksp = (1.0*10-26)*1/(1.0*10-28) = 100 (ans). d) We have [H2S] = 0.10 M and pH = 2.00. We define pH as pH = -log [H+] ====> 2.00 = -log [H+] ====> [H+] = antilog (-2.00) = 0.01 M Since Ka (H2S) is extremely small, we may assume the equilibrium concentration of H2S to be equal to 0.10 M; hence, we have Koverall = [H+]2/[Cd2+][H2S] ====> 100 = (0.01)2/[Cd2+].(0.10) ====> [Cd2+] = (0.01)2/(100*0.10) = 1.0*10-5 The concentration of Cd2+ at equilibrium is 1.0*10-5 M (ans)..
