### Leetcode Problem Solution

• 1. Week 5 • Cheapest Flights within k stops • Merge K sorted Lists • Race Car
• 2. Cheapest Flights within k stops • There are n cities connected by m flights. Each flight starts from city u and arrives at v with a price w. • Now given all the cities and flights, together with starting city src and the destination dst, your task is to find the cheapest price from src to dst with up to k stops. If there is no such route, output -1.
• 3. Example: The cheapest price from city 0 to city 2 with at most 1 stop costs 200, as marked red in the picture.

• 8. // Adjacency Matrix // Calling DFS through solve function // Graph Generation // Visited Array // Keep track of the minimum cost // Cost Matrix
• 9.
• 10. Merge K sorted Lists • You are given an array of k linked-lists lists, each linked-list is sorted in ascending order. • Merge all the linked-lists into one sorted linked-list and return it.

• 29. Race Car • Your car starts at position 0 and speed +1 on an infinite number line. (Your car can go into negative positions.) • Your car drives automatically according to a sequence of instructions A (accelerate) and R (reverse). • When you get an instruction "A", your car does the following: position += speed, speed *= 2. • When you get an instruction "R", your car does the following: if your speed is positive then speed = -1 , otherwise speed = 1. (Your position stays the same.) • For example, after commands "AAR", your car goes to positions 0- >1->3->3, and your speed goes to 1->2->4->-1. • Now for some target position, say the length of the shortest sequence of instructions to get there.
