Given a number, check whether the product of digit sum and reverse of digit sum equals the number or not.
Input : 1729 Output : Yes Explanation: digit sum = 1 + 7 + 2 + 9 = 19 Reverse of digit sum = 91 Product = digit sum * Reverse of digit sum = 19 * 91 = 1729 Input : 2334 Output : No
1. Find the sum of digits of given number.
2. Reverse the digit sum output.
3. Product of digit sum and reverse of digit sum.
If product equals to the original number then print “Yes” else print “No”.
