In this post, we will solve The Love-Letter Mystery HackerRank Solution. This problem (The Love-Letter Mystery) is a part of HackerRank Problem Solving series.

## Solution – The Love-Letter Mystery – HackerRank Solution

### C++

```#include<iostream>
#include<string>
#include<algorithm>
using namespace std;

int main()
{
int t;
cin >> t;
while (t--)
{
string str;
cin >> str;
int len = (int)str.size(), ans = 0;
for (int i = 0, j = len - 1; i < j; i++, j--)
ans += abs((int)str[i] - (int)str[j]);
cout << ans << endl;
}
return 0;
}
```

### Python

```#!/bin/python3

import sys

def theLoveLetterMystery(s):
string = list(s)
res = 0
first = []
second = []

if len(string) % 2 == 1:
first = list(map(lambda x: ord(x), string[:len(string)//2]))
first = first[::-1]
second = list(map(lambda x: ord(x), string[len(string)//2 + 1:]))
else:
first = list(map(lambda x: ord(x), string[:len(string)//2 - 1]))
first = first[::-1]
second = list(map(lambda x: ord(x), string[len(string)//2 + 1:]))
res = abs(ord(string[len(string)//2 - 1]) - ord(string[len(string)//2]))

for ind in range(len(first)):
if first[ind] != second[ind]:
res += abs(first[ind] - second[ind])
first[ind] = min(first[ind], second[ind])
second[ind] = first[ind]

return res

q = int(input().strip())
for a0 in range(q):
s = input().strip()
result = theLoveLetterMystery(s)
print(result)
```

### Java

```import java.io.*;
import java.util.*;
import java.text.*;
import java.math.*;
import java.util.regex.*;

public class Solution {

static int theLoveLetterMystery(String s){
int counter = 0;
int i = 0;
int j = s.length() - 1;

while (i <= j) {
if (s.charAt(i) != s.charAt(j)) {
counter += Math.abs(((int) s.charAt(i)) - ((int) s.charAt(j)));
}
i++; j--;
}

return counter;
}

public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int q = in.nextInt();
for(int a0 = 0; a0 < q; a0++){
String s = in.next();
int result = theLoveLetterMystery(s);
System.out.println(result);
}
}
}
```
