Given an integer matrix, find the length of the longest increasing
path.
From each cell, you can either move to four directions: left, right,
up or down. You may NOT move diagonally or move outside of the
boundary (i.e. wrap-around is not allowed).
Solution: do dfs t...

In order to learn a bit more of Prolog, I implemented the echo command for SWI-Prolog.
I want a correct implementation, that is, it satisfies the following requirements:
It makes only one I/O call so that messages will not be garbled if multiple processes write to the same file.
If it is called...

The idea is to accept an English string of math operations and evaluate them.
