Program: Write code for the following:

For a string, e.g., "1462", calculate from the rightmost digit to the left in this manner: 2 + (62) + 4 + (12). [Where every digit should be multiplied by 2 if it's an even digit, and the sum should be divided by 10. If the quotient is 0, then print true; otherwise, print false.] 1462 = 2 + (62) + 4 + (12) = 20 % 10 = 0 (true) 1764526 = 6 + (22) + 5 + (42) + 6 + (7*2) + 1 = 44 % 10 != 0 (false)
