Share
easy - accepted / - tried
Can you write your own Math.pow() ? The power would only be integers.
pow(1, 2)// 1pow(2, 10)// 1024pow(4, -1)// 0.25
All inputs are safe.
Follow-up
You can easily solve this problem by multiplying the base one after another, but it is slow.
For power of n
, it is needed to do the multiplication n
times, can you think of a faster solution ?
