PYTHON round

PYTHON round
For
this problem,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.Given 3 ints,a b c,return the sum of
their rounded values.To avoid code repetition,write a separate helper
"def round10(num):" and call it 3 times.
Example Output:round_sum(16,17,18) → 60round_sum(12,13,14) → 30round_sum(6,4,4) → 10
