Part I Assume that a N × M matrix is stored in a file. However, the file is corrupted somehow, and some numbers replaced with asterisk symbol (*). Write a method that reads given corrupted file and fills the missing data with the average of the column. For example, given matrix 1 2 3 4 7 8 10 11 12, missing data should be replaced with 2+8+11 = 7.

Question
Part I
Assume that a N × M matrix is stored in a file. However, the file is corrupted somehow,
and some numbers replaced with asterisk symbol (*).
Write a method that reads given corrupted file and fills the missing data with the average
of the column. For example, given matrix
1
2 3
4
6
7
8
10 11 12,
missing data should be replaced with 2++11 = 7.
Part II
Assume that multiple messages are encrypted with Ceaser ciphering' and stored in a file.
Write a method that deciphers the messages with given shift value.
Note: Use English alphabet with only lower-case characters.
