WebJun 27, 2024 · 1. Overview. Trying to find the n-th root in Java using pow () is inaccurate in some cases. The reason for that is that double numbers can lose precision on the way. Hence we may need to polish the result to handle these cases. 2. The Problem. Suppose we want to calculate the N-th root as: base = 125, exponent = 3.

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. photo of rifleWebMar 20, 2024 · This is because the function fact() has a time complexity of O(N), and it is called twice for each call to nCr().
