Algorithms. Problem - a well defined task.. Sort a list of numbers.. Find a particular item in a list.. Find a winning chess move.. Algorithms. A series of precise steps, known to stop eventually, that solve a problem.. Programming - Purpose, structure and the outline of a program.. An overview – programming is: . analysis of a scenario/problem. defining a specification. identifying input, process and output testing/debugging.. 1. Brute Force.
