C/C++ Greedy Algorithms Programs

n greedy algorithms, the solution is constructed by choosing the current optimal solution without worrying about its effect in the future. The principle of greedy algorithms is that the local optimum may lead to the global optimum.

In this article, we will discuss some common Greedy algorithms practice problems in C/C++ language.
