The first character has an index value of 0.

Note: Use the Special String Operators for string concatenation, string inclusion, and simple comparison.

Parameters

• The first parameter is the string.

• The second parameter is a number representing the start index.

• The third optional parameter is a number representing the stop index.

Output

• If the stop index parameter is specified, the substring starting with the character at the start index and ending one character before the stop index is returned.

• If the stop index parameter is not specified, the substring from the start index to the end of the string is returned.
