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 +++--+ |
