Write a program to enter two numbers and check whether they are co-prime or not.
[Two numbers are said to be co-prime, if their HCF is 1 (one).]
Sample Input: 14, 15
Sample Output: They are co-prime.A prime number is said to be 'Twisted Prime', if the new number obtained after reversing the digits is also a prime number. Write a program to accept a number and check whether the number is 'Twisted Prime' or not.
Sample Input: 167
Sample Output: 761
167 is a 'Twisted Prime'.
