Algorithmic solution a series of well defined steps to solve a particular type of problem is called an algorithm. The algorithm problem solving approach in psychology. Great programmers are able to conceptually come up with solutions by visualizing and breaking down the problem into smaller parts. To sort an array in increasing order, a sequential order of steps is followed, so this type of solution is an algorithmic solution.

While algorithms provide stepbystep procedures that can guarantee solutions, heuristics are faster and provide shortcuts for getting to solutions, though this has the potential to cause errors.
