Merge Sort Implementation
Implement merge sort from scratch, including the merge step for two sorted halves.
Input format
The first line contains N. The second line contains N space-separated integers.
Output format
Print the array sorted in non-decreasing order, space-separated on one line.
Constraints
- Values fit in a 64-bit signed integer
- Trailing whitespace and a trailing newline are ignored by the judge
Read from stdin, write to stdout. Sample cases below show the exact format.
