Write a Java program that implements static method roundSum() so that given 3 ints: a, b, and c; return the sum of their rounded values. We'll round an int value up to the next multiple of 10 if its rightmost digit is 5 or more, so 15 rounds up to 20. Alternately, round down to the previous multiple of 10 if its rightmost digit is less than 5, so 12 rounds down to 10. roundSum(16, 17, 18) → 50 roundSum(12, 13, 14) → 40 roundSum(6, 4, 4) → 10 The examples of input and output you can see in the picture. (the code structure should be as in the second picture)
