Problem: Left and Right Sum
Write a program that converts 2 * n integers and checks whether the sum of the first n integers (left sum) equals the sum of the second n numbers (right sum). In case the sums are equal, print "Yes" + the sum, otherwise print "No" + the difference. The difference is calculated as a positive number (by absolute value). The format of the output must be identical to the one in the examples below.
Sample Input and Output
| Input | Output | Input | Output |
|---|---|---|---|
| 2 10 90 60 40 |
Yes, sum = 100 | 2 90 9 50 50 |
No, diff = 1 |

Hints and Guidelines
We will first input the number n, after that the first n numbers (left half) and sum them up. We will then proceed with inputting more n numbers (the right half) and sum them up. We calculate the difference between the sums by absolute value: Math.Abs(leftSum - rightSum). If the difference is 0, print "Yes" + the sum, otherwise print "No" + the difference.
