 // 1-implement the function mult that takes a single parameter n, and computes the multiplication of all integers up to n

 mult(3); // => 6
 mult(4); // => 24

 // your code is here

// 2- Use a while loop to build a single string with the numbers 1 through n
// separated by the number next to the current number. 
//Have it return the new string.
