Idea: There is no need to use simulation to write this question. In fact, the final result has nothing to do with the direction of the first ant's head.
There are only two situations where other ants will catch a cold:
1. Be on the right side of the first ant and walk to the left.
2. Go to the left of the first ant and go to the right.

int cnt = 1;
for(int i=1;i<n;i++){
if(abs(a[0])<abs(a[i])&&a[i]<0){

}
if(abs(a[0])>abs(a[i])&&a[i]>0){
