Approach


i)create a method power which takes base and exponent as arguments
ii)if exponent is 0 return 1 if exponent is 1 return base
iii) calculate power (base,exponent/2) and store in r
iv)if exponent is even return r*r else return r*baser

v)in main method take base and exponent as input from the user

Time Complexity: O(log m)
Space Complexity: O(1)
