import java.util.Arrays; public class Main { public static void main(String[] args) {

    int[] a = {1,2,3,0,0,0};
    int[] b = {7,9,13};
    
    //resultant array: a={1,2,3,7,9,13}

}

CodePudding user response：

Iterate through array A and replace elements with value zero with elements from B.

int n = a.length();
int m = b.length();
int j = 0;
for(int i=0; i<n; i  ){
  if(a[i] == 0 && j<m){a[i]=b[j];j  ;}
}
