Solve: Two Char
Given a String and an int index, return the substring of length 2 starting at the given index
in the passed String.
If the index is too big or too small to define a valid substring, use the first 2 characters.
The string length will be at least 2.
fun twoChar(
str: String,
index: Int,
): String {
return "" // You may need to remove this starter code
}
