Represent N as sum of K even numbers | Java implementation to represent N as sum of K even numbers ; Function to print the representation ; N must be greater than equal to 2 * K and must be even ; Driver Code
import java . util . * ; class GFG { static void sumEvenNumbers ( int N , int K ) { int check = N - 2 * ( K - 1 ) ; if ( check > 0 && check % 2 == 0 ) { for ( int i = 0 ; i < K - 1 ; i ++ ) { System . out . print ( "2 ▁ " ) ; } System . out . println ( check ) ; } else { System . out . println ( " - 1" ) ; } } public static void main ( String args [ ] ) { int N = 8 ; int K = 2 ; sumEvenNumbers ( N , K ) ; } }
