Given a string str. The task is to check whether it is a binary string or not. 
Examples: 
 

Input: str = "01010101010"
Output: Yes

Input: str = "geeks101"
Output: No

Split a string can be quite useful sometimes, especially when you need only certain parts of strings. A simple yet effective example is splitting the First-name and Last-name of a person. Another application is CSV(Comma Separated Files). We use split to get data from CSV and join to write data to CSV.

Given the string, we have to remove the i^th indexed character from the string.

In any string, indexing always start from 0. Suppose we have a string geeks then its indexing will be as –

g e e k s
0 1 2 3 4

A string is given, and you have to find all the words (substrings separated by a space) which are greater than the given length k.

us the methods to find the frequency of maximum occurring character in a python string. This is quite important utility nowdays and knowledge of it is always useful. Let’s discuss certain ways in which this task can be performed.

This article gives us the methods to find the frequency of minimum occurring character in a python string. This is quite important utility nowdays and knowledge of it is always useful. Let’s discuss certain ways in which this task can be performed.

We are given a string and we need to remove all duplicates from it? What will be the output if the order of character matters?
Examples:

Input : geeksforgeeks
Output : efgkos

Given a pair of non empty strings. Count the number of matching characters in those strings (consider the single count for the character which have duplicates in the strings). Examples:

Input : str1 = 'abcdef'
        str2 = 'defghia'
Output : 4 
(i.e. matching characters :- a, d, e, f)

Input : str1 = '[email protected]'
        str2 = '[email protected]'
Output : 5 
(i.e. matching characters :- b, 1, 2, @, k)

Given a string, the task is to check if every vowel is present or not. We consider a vowel to be present if it is present in upper case or lower case. i.e. ‘a’, ‘e’, ‘i’.’o’, ‘u’ or ‘A’, ‘E’, ‘I’, ‘O’, ‘U’ . 

Given a string. The task is to print all words with even length in the given string. Examples:
Input: s = “This is a python language” Output: This is python language Input: s = “i am muskan” Output: am muskan
