hello @lovely

u r never updating ur y.
ie ur y will never become 0 , due to which the loop will keep running and hence the tle

btw u can easily solve ths proble using stirng.

read a number as string (say s) .
if left most character is ‘9’

  • then leave the leftmost character as it is and for other characters simpl replace s[i] with min(s[i],‘9’-s[i])

else:

  • for each i replace s[i] with min(s[i],‘9’-s[i])

print s

#include<bits/stdc++.h>

using namespace std;

int main() {

    string n;

    cin>>n;

    int start=0;

    if(n[0]=='9')

       start=1;

    for(int i=start;i<n.length();i++){

            char c='9'-n[i]+'0';

            n[i]=min(n[i],c );

    }

    cout<<n;

    return 0;
