Extracted text: Cryptography, at its most fundamental level, requires two steps: encryption and decryption. The encryption process uses a cipher in order to encrypt plaintext and turn it into ciphertext. Decryption, on the other hand, applies that same cipher to turn the ciphertext back into plaintext. One of the simplest forms of encryption known as shift cipher. With this cipher, we simply shift each letter a set number of spaces up or down the alphabet. a bc d. hij kI e m n p r u V X y Z Letters shifted by 4 positions. y a d e f g i i k m| n p r u V Write a function which encrypts a lowercase word by using shift cipher algorithm. The name of the function should be ShiftCipherEncrypt. It has two input arguments (s) and (n), one output argument (t). The input argument (s) should be the text to be encrypted. The input argument (n) should be equal to the number of positions to be shifted. The output argument (f) should be the text which is encrypted. Examples: s= 'basic' , n = 1 , t = 'azrhb' s = 'computer' , n = 3 , t = 'zljmrqbo' s= 'programming' , n = 5 , t = 'kmjbmvhhdib'
