sorting

PROBLEM:

Consider A number N with C digits. The number N is said to be Stronger if Reverse of that number is equal to the original number otherwise
it is considered Weaker. If the Number is Stronger Print C^C or if the Number is Weaker Print CXC.

EXPLANATION:

Read a String s, take a integer array of string length convert the string into integer array by subtracting each character with ‘/0’(null character) ie converting based on ASCII values in a for loop, sort the array using sort() function. then print each array element by type casting it to character using a for loop. OR u can directly use sort() function on the String itself.

Setter's Solution
``````#include <bits/stdc++.h>
#include <math.h>
using namespace std;

#define ll long long
#define ff first
#define ss second
#define pb push_back
#define vi vector<int>
#define vll vector<long long int>

int main()
{
#ifndef ONLINE_JUDGE
freopen("in.txt", "r", stdin);
freopen("out.txt", "w", stdout);
#endif

std::ios::sync_with_stdio(false);

int t;
cin >> t;
while (t--)
{
string s;
cin >> s;
int arr[s.length()];
for (int i = 0; i < s.length(); i++)
{
arr[i] = s[i] - '\0';
}
sort(arr, arr + s.length());
for (int i = 0; i < s.length(); i++)
{
cout << (char)arr[i];
}
cout << endl;
}
}
