Can you also explain it because i don't understand. thank you

Simulate over the pseudocode to produce output when A = [2, 5, 9, 17, 23, 44, 45, 57], k = 45, s = 0, and e = 7. Show each step of your calculation. Function_01 (A, k, s, e) Input: a. A: a sorted array of integers b. key-value k provided by users c. start index s of the array d. end index e of the array output: The index of the key value Steps: if e A[mid] then return Function_01 (A, k, mid + 1, e) d. else return mid
