Write a Python program to first take an integer number (x), where 1 x 255, from the user by using the prompt "Number of registers in the CPU:". Use try- except block to wait indefinitely until the given input is an integer. Check the validity of the range of the input in a user defined function 'check_range'. Now, call a function 'find_n' to find out a positive number (n) such that 2n is the least integer greater than or equal to x. Display the value of n with prompt "The number of bits for the Register field in the Instruction format is:"
