A positive number is a very simple algorithm that is being asked sometimes in interviews to understand the basic logic of employees.

The question for an algorithm is, 


Given an integer x, return positive/negative. The algorithm should return 'true' for positive numbers and "false" for negative numbers.


Example 1:

Input: x=123

Output: true


Example 2:

Input: x = -123

Output: false


Let's start with the algorithm,


var isPositive = function(x) {

    if(x > 0){

        return true;

    }

    return false;

};


Here, we have just checked that x is greater than zero(0) then the number becomes positive. 


I hope you understood the algorithm for positive and negative, if you have any doubts please ket us know in the comments.
