You are given a 2D array $A$ with $n$ rows and $m$ columns. For each column, calculate its sum.
### Input
- The first line contains 2 integers $n, m$.
- Next $n$ lines, each line contains $m$ integers of $A$.
### Output
- Print $m$ integers, $i^{th}$ integers is the sum of $i^{th}$ column.
### Constraints
- $1 \le n, m \le 100$.
- $|A_{i,j}| \le 100$.
### Example
