Write a program that determines how many positive and negative integers have been entered and calculates the total and average of all the entered numbers. code example

Example 1: Given two integers a and b, which can be positive or negative, find the sum of all the integers between including them too and return it. If the two numbers are equal return a or b.

getSum(1,3)
 1 + getSum(2,3)
 1 + ( 2 + getSum(3,3))
 1 + ( 2 + (3))

Example 2: Given two integers a and b, which can be positive or negative, find the sum of all the integers between including them too and return it. If the two numbers are equal return a or b.

function getSum( a,b ){
   if (a == b) return a; //(1)
   if (a < b) {
      return a + getSum(a+1, b); //(2)
   }else {
      return a + getSum(a-1,b); //(3)
   }
}

getSum(1,3)
