Explain the code and provide the output int sum = new int44; for int k = 0; k 4; k++ sumk0 = 1; for int k = 0; k 4; k++ sum0k = 1; for int m = 1; m 4; m++ for int n = 1; n 4; n++ summn = summ-1n

This code creates a 4x4 array called "sum" and initializes the first row and first column with 1's. It then uses a nested for loop to fill in the rest of the array using a formula that adds the value to the left and above the current cell. Finally, it prints out the values in the last row of the array (excluding the first element) separated by spaces.

The output of this code is: 1 2 3
