Encrypt the message CINEMA using the RSA system with n=17*11 and e=13 translating each letter into integers starting with A=10, and working with blocks of one letter each

51. Prepare a datafile for the ADJUST program to solve the following horizontal network. 4323.793 4148 349 4558.156 Az90d 3086.928 R 6983.374, 0.000 2165 823 287.737

need some help,thank you in advance!

write an encoder and a decoder for a modified "book cipher." A book cipher uses a document or book as the cipher key, and the cipher itself uses numbers that reference the words within the text. For example, one of the Beale ciphers used an edition of The Declaration of Independence as the cipher key. The cipher you will write will use a pair of numbers corresponding to each letter in the text. The first number denotes the position of a word in the key text (starting at 0), and the second number denotes the position of the letter in the word (also starting at 0). For instance, given the following key text (the numbers correspond to the index of the first word in the line)   [0] 'Twas brillig, and the slithy toves Did gyre and gimble in the wabe; [13] All mimsy were the borogoves, And the mome raths outgrabe. [23] "Beware the Jabberwock, my son! The jaws that bite, the claws that catch! [36] Beware the Jubjub bird, and shun The frumious Bandersnatch!" [45] He took his vorpal sword in…
