Please explain the solution to the following Scheme programming problem:

3. Given the following recursive Scheme function: (define (my-expnt) (cond ((= t 0) 1) (else (* n (my-exp n (- t 1)))))) Re-write this as a tail-recursive Scheme function. Solution: (define (my-exp-tnt) (define (helper n t accumulate) (cond ((= t 0) accumulate) (else 3.
