WebJun 26, 2024 · The function factorial finds the factorial of the number n using a while loop. Then it returns fact. The code snippet that demonstrates this is given as follows − static int factorial(int n) { int fact = 1; int i = 1; while(i <= n) { fact *= i; i++; } return fact; } WebAnswer = 81 Here, instead of using a while loop, we've used a for loop. After each iteration, the exponent is decremented by 1, and the result is multiplied by the base exponent number of times. Both programs above do not work if you have a negative exponent. For that, you need to use the pow () function in Java standard library.
