Prove the Correctness of Greedy Algorithms

Learn how to prove the correctness of greedy algorithms.

Restricted search space

A greedy algorithm restricts the search space by selecting the most profitable piece of a solution at each step. For example, the LargestConcatenateLargestConcatenate algorithm only considers concatenations starting from the largest digit instead of considering all possible concatenations. Instead of all possible ways of changing money, the ChangeChange algorithm considers only the ones that include a coin with the largest denomination (that does not exceed moneymoney).
