MCQ Practice
What will be the value stored in arr[2][2] when the following code is executed? #include int get_ways(int num_of_dice, int num_of_faces, int S) { int arr[num_of_dice + 1][S + 1]; int dice, face, sm; for(dice = 0; dice <= num_of_dice; dice++) for(sm = 0; sm <= S; sm++) arr[dice][sm] = 0; for(sm = 1; sm <= S; sm++) arr[1][sm] = 1; for(dice = 2; dice <= num_of_dice; dice++) { for(sm = 1; sm <= S; sm++) { for(face = 1; face <= num_of_faces && face < sm; face++) arr[dice][sm] += arr[dice - 1][sm - face]; } } return arr[num_of_dice][S]; } int main() { int num_of_dice = 3, num_of_faces = 4, sum = 6; int ans = get_ways(num_of_dice, num_of_faces, sum); printf("%d",ans); return 0; }
