String slicing in Python to check if a string can become empty by recursive deletion

Given a string “str” and another string “sub_str”. We are allowed to delete “sub_str” from “str” any number of times. It is also given that the “sub_str” appears only once at a time. The task is to find if “str” can become empty by removing “sub_str” again and again. Examples: Input : str = "GEEGEEKSKS", sub_str = "GEEKS" Output : Yes Explanation :

String slicing in Python to Rotate a String

Given a string of size n, write functions to perform following operations on string. Left (Or anticlockwise) rotate the given string by d elements (where d <= n).Right (Or clockwise) rotate the given string by d elements (where d <= n).Examples: Input : s = "GeeksforGeeks" d = 2Output : Left Rotation : "eksforGeeksGe" Right Rotation : "ksGeek

Python | Check if given string can be formed by concatenating string elements of list

Given a string 'str' and a list of string elements, write a Python program to check whether given string can be formed by concatenating the string elements of list or not. Examples: Input : str = 'python' lst = ['co', 'de', 'py', 'ks', 'on'] Output : False Input : str = 'geeks' lst = ['for', 'ge', 'abc', 'ks', 'e', 'xyz'] Output : True Approach #1

Python | Check if string ends with any string in given list

While working with strings, their prefixes and suffix play an important role in making any decision. For data manipulation tasks, we may need to sometimes, check if a string ends with any of the matching strings. Let's discuss certain ways in which this task can be performed. Method #1 : Using filter() + endswith() The combination of the above func

Python | Sorting string using order defined by another string

Given two strings (of lowercase letters), a pattern and a string. The task is to sort string according to the order defined by pattern and return the reverse of it. It may be assumed that pattern has all characters of the string and all characters in pattern appear only once. Examples: Input : pat = "asbcklfdmegnot", str = "eksge" Output : str = "g
