gets the first substring which starts and ends with the given values.

@param inputString
the string from which the substring will be
extracted.
@param startingWith
to match the starting substring
@param endingWith
to match the ending substring
@return the substring which starts and ends with the given
{@code startingWith} and {@code endingWith} values. Or returns
null if it doesn't contain.
