# 76. Strings

## I'm a slow walker, but I never walk backwards.

Given some strings, sort them by strcmp and strcpy/qsort then output.

## Input format

There are strings in the input, one per line, with no more than $32$ characters each. Note that there could be spaces in each line, so you should use fgets or gets to read the input. And you should determine the number of strings using the return value NULL of fgets/gets. The number of strings is no more than $64$.

## Output format

The sorted strings, one per line.
