Write a program to calculate pow ( x , n ) |  ; Function to calculate x raised to the power y ; Program to test function power
class GFG { static int power ( int x , int y ) { if ( y == 0 ) return 1 ; else if ( y % 2 == 0 ) return power ( x , y / 2 ) * power ( x , y / 2 ) ; else return x * power ( x , y / 2 ) * power ( x , y / 2 ) ; } public static void main ( String [ ] args ) { int x = 2 ; int y = 3 ; System . out . printf ( " % d " , power ( x , y ) ) ; } }
