Write a program to accept a number and check if it is a Mark number or not. A number is said to be Mark when the sum of the squares of each digit is an even number as well as the last digit of the sum and the last digit of the number given is the same. Example: n = 246 sum = 2 x 2 + 4 x 4 + 6 x 6 = 56 56 is an even number as well as last digit is 6 for both sum as well as the number.
