NestedFor loop - Java Quiz Question

Correct Answer : C

Inside main two integer variables, sum and i are declared and initialized to 5 and 1 respectively. The next statement is a for loop with empty initialization part and has a terminating condition : i < 4. There are 2 more for loops nested inside this loop. The first nested loop has initialization condition j = 1 and terminating condition j < 4. The second nested loop has initialization condition of k = 1 and terminating condition k < 4 - 1 = 3 and increment value 1(k++). For every iteration, sum is multiplied with i * j. Then i, j, k are incremented sequentially.
For each iteration, value of sum will be as follows:
sum = 5 * 1 * 1 = 5
sum = 5 * 2 * 2 = 20
sum = 20 * 3 * 3 = 180

Then loops terminate since the values of i, j and k will be 4 and none of the termination conditions satisfy. So the value Sum = 180 will be displayed using display statement.
