hi everyone..i need to crack a symmetric key by implementing a method called CrackSymmetricKey

I must use the TEA encryption algorithm below:

```
union myMsgType{
unsigned long textConverted[2];
char text[9];
};
class TEA_Algorithm
{
public:
void CrackSymmetricKey(union myMsgType plaintext, union myMsgType ciphertext);
void Decrypt(unsigned long k[], unsigned long ciphertext[], unsigned long plaintext[]);
void Encrypt(unsigned long k[], unsigned long plaintext[], unsigned long ciphertext[]);
TEA_Algorithm() {};
virtual ~TEA_Algorithm() {};
};
```

As input, im given the following ciphertext and i need to find the secret key that has been used to obtain this ciphertext, and hence, deduce the original plaintext.

// myCiphertext.textConverted[0] = 2022673309;

// myCiphertext.textConverted[1] = 3810199360;

```
#include "stdafx.h"
#include <iostream>
#include <string.h>
using namespace std;
#include "TEA_Algorithm.h"
void TEA_Algorithm::Encrypt(unsigned long k[], unsigned long plaintext[], unsigned long ciphertext[])
{
unsigned long y = plaintext[0], z = plaintext[1];
unsigned long delta = 0x9e3779b9, sum = 0; int n;
for (n= 0; n < 32; n++) {
sum += delta;
y += ((z << 4) + k[0]) ^ (z+sum) ^ ((z >> 5) + k[1]);
z += ((y << 4) + k[2]) ^ (y+sum) ^ ((y >> 5) + k[3]);
}
ciphertext[0] = y; ciphertext[1] = z;
}
void TEA_Algorithm::Decrypt(unsigned long k[], unsigned long ciphertext[], unsigned long plaintext[])
{
unsigned long y = ciphertext[0], z = ciphertext[1];
unsigned long delta = 0x9e3779b9, sum = delta << 5; int n;
for (n= 0; n < 32; n++) {
z -= ((y << 4) + k[2]) ^ (y + sum) ^ ((y >> 5) + k[3]);
y -= ((z << 4) + k[0]) ^ (z + sum) ^ ((z >> 5) + k[1]);
sum -= delta;
}
plaintext[0] = y; plaintext[1] = z;
}
void TEA_Algorithm::CrackSymmetricKey(union myMsgType plaintext, union myMsgType ciphertext)
{
void CrackSymmetricKey(union c);
/*
what should i write here if this is what's given:
plaintext:= security
ciphertext:
myCiphertext.textConverted[0] = 2022673309;
myCiphertext.textConverted[1] = 3810199360;
additional information: key[0]=key[1]=k[2]=k[3]
and you're asked to determine what is the secret key that
has been used to encrypt this plaintext.
*/
}
```

plz help..i know i should make a loop inside but im very weak in programming
