Mobile coding works. A laptop is faster for long sessions.
Problem
Read from standard input two natural numbers `n` and `k`, then `n`
integers in an array. Rotate the array `k` positions to the left and
print the result.
One left rotation moves the first element to the end. Rotating by `k`
positions repeats this operation `k` times (equivalently, position `i`
in the result corresponds to position `(i + k) % n` in the original array).
Input format
Input
input.txt
The first line contains `n` and `k` separated by a space. The second line contains `n` integers separated by spaces. - `1 <= n <= 1000` - `0 <= k <= 1000000` (may be larger than `n`) - array values are integers between `-1000000` and `1000000`
Output format
Output
output.txt
The program prints to standard output the `n` elements of the rotated array, separated by spaces, followed by a newline.
