Prog sum of integers --- Introduction ---

This modules gathers interactive programming exercises, variable and configurable, on the subject of computing a list of integers. The software can ask you to produce an algorithm to make a partial or total sum of the list, according to various formulas. It will then compile your submitted code and test it on randomly generated lists for the validity of the code. New comers may start by testing the most standard case.
