ALGORITHM

• Definition of algorithm: in computer science, an algorithm is a series of instructions, for solving problems step by step.

• The goal of an algorithms is the purpose of an algorithm, in this example it is counting persons in a room.

• Pseudo code is an english like instruction set the sintaxis that resembles the programing language

• The variable is the thing that I would like to measure. In this case the variable N is the quantity of persons in the same room.

• How to test the algorithm? First, in the line 1 stablish a variable to be measured, in the line 2 is for each person is in the room we count 1, and finally int he line 3 you must say how we are going to count the variable.

• The loop is a sequence of steps that will be repeated a number of times.

• Testing algorithm: You must establish if the algorithm works so you bang on it a bit testing corner cases or specific cases. 

• The corner case is a case that is not typical. To test the corner cases they try to know if the algorithm functions with 0 persons in a room.

• The branch is a new condition that you establish in a new line (line 4) when an algorithm doesn´t function.
