In the following pseudocode, let A be an array of positive integers, low is the first index of A high is the last index of A and x is a positive integer number and the function returns an nteger. Using the following test case, explain what the Mystery function does. Find a loose upper bound as its time complexity. A=[3,7,2,4], x=7. Show all steps of compiling the function to find the output. nt Mystery (x, low, high, A) { if (x == 0) { return 1; } n = high low + 1; if (x < 0 || n == 0) { return 0; } return Mystery (x - A[low], low, high, A) + Mystery (x, low + 1, high, A);
