<p> <span style="font-family:'Times New Roman', serif;font-size:10.5pt;line-height:150%;">&nbsp;Give you many positive integer N (N&lt;=23), for each N, just output N*(N+1)/2 integers in a single line, separated by space. (Don't ask me why.) For each N, the output line contains integers from 1 to N, and each just once. Again, do not ask me why, thank you. I'm so busy. But I can tell you a secret, the output has relationship with number triangle.
