Please help with writting a simple C++ code for ebcrypting and decrypting this Ciphertext. Thank you

(Extra Credits) Write a C/C++ program hillCipher to decrypt the ciphertext below which was encrypted using a Hill ipher with m 2: LMQETXYEAGTXCTUIEWNCTXLZEWUAISPZYVAPEWLMGQWYA XFTCJMSQCADAGTX LMDXNXSNPJQSYVAPRIQSMHNOCV AXFV Note: use digram frequencies. The 10 digrams with highest frequencies in English are (in the order of decreasing frequency) TH, HE, IN, ER, AN, RE, ED, ON, ES, ST. Design the program to try the more likely possibilities first. Your program should work interactively with the user (show potential plaintext after each try) and stop when the user is satisfied with the result
