When the option is valid, then break the loop, otherwise, it will ask for the input repeatedly.You should take the input as an integer, for that you need to typecast the input to an integer using int() method.ExamplePlease check the code to follow the given points.print("Come-on in.

This algorithm is named Z Algorithm because, in this algorithm, we need to create a Z array. The size of the Z array is the same as the text size. This array is used to store the length of longest possible substring starting from the current character of the main string. At first, the pattern and the main text are concatenated with a special symbol which is not present in the text and pattern.
