Please help with the following coding assignment. Thanks so much I just need part 2

The solution to part 1 is Key 21 decoded to "GO CYBEREAGLES"

Decipher the following text produced by a Caesar cipher. Code to compute correlation of frequency for cryptanalysis. OR Code to use brute force with exhaustive key. LT HDGJWJFLQJX (show spaces in proper place) The following was enciphered with a Vignere cipher. Find the key and decipher it. Code to compute Index of Coincidence (IC) and determine period. You may work on part of it by hand (like which IC to choose). OR Work by hand to use repetitions to find largest common factor to guess period. For both: Total of 3 points You may reuse work from question 1 here once you have found the period and split the alphabets accordingly. Show your work in detail.
