Build a trie of the following terms using: a. A pointer representation (each node points to its children) b. A Leftmost-Child-Right-Sibling representation at, ate, attack, atop, amp, amuse, be, bet, bide Construct an expression tree for the following equation: (a * b) + 9d * -e) Solution Answer Construct an expression tree for the following equation (a*b) +(d*-e) Here expression is the Infix expression , we can create expression tree using operands like +,-,* (a*b) +(d*-e) Infix expression tree + * * a b - e .
