In this quiz, you'll check your understanding of the best way to check whether a Python string contains a substring. You'll also revisit idiomatic ways to inspect the substring further, match substrings with conditions using regular expressions, and search for substrings in pandas. ...

// Method to perform a specific operation on the input string public static string test(string str) { // Check if substring from index 1 to index 2 (exclusive) is "yt" // If true, remove characters at index 1 and 2 from the string; otherwise, return the original string return str....
Write a Scala program to check whether a given substring presents in the middle of another given string. Here middle means difference between the number of characters to the left and right of the given substring not more than 1. Sample Solution: ...
Instead, the find() method is associated with strings, used to locate the position of a substring within a string. For checking if an element exists in a list, Python developers typically use the in operator , the count() method, or implement a loop to iterate through the list to check...
