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 +++--+ |
