A full-length n sequence 0, m times modified for this sequence, each modification, I would specify a starting point x, you start from this starting point, each subsequent sequence number incremented by 1, plus 2, plus 3 ... "z
Input formats:
The first line two positive integers n (n <= 100000), m (m <= 100000),
followed m rows, each is a positive integer x (1 <= x <= n), each modification is starting point.Output formats:
Output line comprises n positive integer representing the last sequence separated by spaces, no extra space end of the line.
Sample input:
Here we are given a set of inputs. E.g:
5 3 2 4 3
Sample output:
Given here corresponding output. E.g:
0 1 3 6 9
