Divisibility of numbers
Given a range
[l; r]
you are asked to print the divisibility for each number in that range (l
and r
including). For each number, you are asked to print a sequence of +
and -
signs. For the number
4
, the output should look like ++-+
, which means that 4 is divisible by 1 (first +
), it is also divisible by 2 (second +
), not divisible by 3 (the -
), and is divisible by itself (the last +
).The input contains 2 numbers the
l
and r
of that range (l ≤ r).The output should contain as many rows as there are numbers in that range. Each row should start with the number it refers to, followed by a sequence of
+
and -
signs.Input | Output |
2
6 | 2 ++
3 +-+
4 ++-+
5 +---+
6 +++--+ |
