Write a function named addDiag that given a square table of n integers, calculates the sum of the numbers on the left-right diagonal and returns it. For instance: int table[MAX][MAX] = { {10, 20, 30, 40}, {50, 60, 70, 80}, {90, 11, 21, 31}, {41, 51, 61, 71} }; int n = 4; // the actual size of the array int sum = addDiag(table, n); After this call sum = 10 + 60 + 21 + 71 = 162;
