Why its not printing anything

Hey @kundankumarsports2
There’s a problem with your for loop in the function-
corrected for loop is-
for(int j=s;j<=e;j++){
if(in[j]==pre[i])
{
index=j;
break;
}
}

first thing, you’ve to compare in[j] with pre[i], you were comparing it with pre[j],
Secondly, you have to run j from s to e,
Now your code will print, just check
