// Write a function cubeSum(n, m) that will calculate a sum of cubes 
// of numbers in a given range, starting from the smaller 
// (but not including it) to the larger (including). 
// The first argument is not necessarily the larger number.

// Examples:

// Test.expect(cubeSum(5,0) == 225, "cubeSum(5,0) should be 225");
// Test.expect(cubeSum(2,3) == 27, "cubeSum(2,3) should be 27");

// My Solution:

function cubeSum(n, m){
	var sum=0;
		if(n>m){
		    for(var i=m+1; i<=n;i++){
		        sum+=i*i*i;
		    }
		}
		else{
		    for(var i=n+1; i<=m;i++){
		        sum+=i*i*i;
		    }
		}
	return sum;	
}

// cubeSum(5,0)

// 1^3 + 2^3 + 3^3 + 4^3 + 5^3

// 1 + 8 + 27 + 64 + 125 = 225

cubeSum(2,3)

// 3^3
