#include <iostream>

int revNumber(int n){
    int newNum = 0;
    while (n > 0){

        n = n/10;
    }
    return newNum;
}

int main(){
    int n;
    cin >> n;
    n = revNumber(n);
    int digit, invertDigit, newNum = 0, index = 1;
    while (n > 0){
        digit = n % 10;
        invertDigit = 9 - digit;

hi @aakshatmalhotra100
just replace int with long long int bcoz constraints are large… it will pass all test cases… rest ur logic is absolutely correct…
