Time Complexity: O(100 * n*sqrt(n)), where n is the number ranging from 1 to 100Auxiliary Space: O(1), as no extra space is required, Time Complexity: O(100 * sqrt(n)), where n is the number ranging from 1 to 100Auxiliary Space: O(1), as no extra space is required, Efficient Solution: Check if a number can be expressed as a^b | Set 2This article is contributed by Vaibhav Gupta. In the above program, we have created the checkPrime () method to check whether a number is prime or not. Now if A is a multiple of 16, it must be a multiple of both 8 and 2 separately. The approach is simple. So 216000 = 60^3. N = a b Taking log both sides: log (N) = b.log (a) b = log (N)/log (a) The problem with the above implementation is that as the number gets bigger, so does the number of iterations.
