You can create an array which holds the chars that you need, in order to connect perfectly with the numbers, the string located. If 'a' is on X array, then we get the 'a' array of Y and set it. Or you could just extend the array.
Code:
new array = {
{ "one", 1 },
{ "two", 2 },
{ "three", 3 },
{ "four", 4 }
}
