Because of the invariance of arrays, the array returned by changing the position of elements is actually a new array.

Public? Class? Test {

Public? Static electricity Invalid? Main (string ...? args){

int[]？ Answer? =? {0,9,0,4,5,0,0, 1 1,2};

int？ Count? =? 0;

for(int？ Me? =? 0; I<a. Length; i++){

What if (a[i]? ! =? 0)

}

for(int？ j？ =? 0? ; J< count? ; ? j++){
