text: Write a program to calculate pow ( x , n ) | Java program for the above approach ; If x ^ 0 return 1 ; If we need to find of 0 ^ y ; For all other cases ; Driver Code
code: import java . io . * ; class GFG { public static int power ( int x , int y ) { if ( y == 0 ) return 1 ; if ( x == 0 ) return 0 ; return x * power ( x , y - 1 ) ; } public static void main ( String [ ] args ) { int x = 2 ; int y = 3 ; System . out . println ( power ( x , y ) ) ; } }
