Given an integer as input, can you round it to the next (meaning, "higher") multiple of 5?
Examples:
    input:    output:
    0    ->   0
    2    ->   5
    3    ->   5
    12   ->   15
    21   ->   25
    30   ->   30
    -2   ->   0
    -5   ->   -5
    etc.
Input may be any positive or negative integer (including 0).
You can assume that all inputs are valid integers.
def round_to_next5(n):

    return (round((n/5)+0.49)*5)
def round_to_next5(n):

    return (round((n/5)+0.49)*5)
