he main difference between algorithm and pseudocode is that an algorithm is a step by step procedure to solve a given problem while pseudocode is a method of writing an algorithm.

An algorithm is a procedure for solving a problem. In other words, it is a sequence of steps to solve a given problem. It can contain sequences, iterations, selection, etc. Usually, there can be several methods to solve the problem. It is important to analyze each solution and select the best approach to solving it. On the other hand, pseudocode is a method of developing an algorithm. Programmers can use informal simple language to write pseudocode and there is no strict syntax to follow. It is a text-based detailed design tool.
