Prove that the algorithm is actually correct "FORMALLY PROVING CODE CORRECTNESS"

Problem 3: Array Reversal We have come through an old algorithm whose name indicates that it reverses the array elements; its pseudo-code was defined as follows: note n := A.length denotes the size of the array, number of items. Algorithm 2 REVERSE-ARRAY(A) while s >0A e < (n – 1) do swap (A[s], A[e]) s + s – 1 e e +1 end while a) Implement the algorithm in Python, and test it b) Empirically, show the performance curve of the algorithm using time measurements c) Using the basics of the theoretical analysis, write the complexity of its worst-case time. d) Prove that the algorithm is actually correct
