SurroundingSquare.js

//TASK

// Complete the function that takes an odd integer (0 < n < 1000000)
// which is the difference between two consecutive perfect squares,
// and return these squares as a string in the format "bigger-smaller"

//EXAMPLE
// 5  -->  "9-4"
// 7  -->  "16-9"
//9  -->  "25-16"
