You should use Python's Hashlib for this purpose. Create an integer s containing all the digits in your student ID. For example, if my student ID is 47141085, then s = 47141085. Let "str" denote the string function, i.e.. given any integers, the function str(s) casts it into a string. For example, s = 47141085 becomes str(s) ="47141085". Set the target t to: t = 2^256/2 ^8 Let H be the SHA-256 hash function. Let r be a counter starting from 1. Finally, let "||" denote string concatenation. (a) Implement a program that tries successive values of r, i.e., r = 1, 2, 3,..., computes H(str(r)||str(s)), compares it with t and halts whenever H(str(r)||str(s))
