How do you check if two strings have a common substring?
Check if two strings have a common substring
- You are given two strings str1 and str2.
- A basic approach runs on O(n^2), where we compare each character in string 1 to each character in string 2 and replace each matching character with a “_” and set the flag variable to true.
- Production :
- Time complexity : O(n)

How do you check if two strings are equal in JS?
Generally, if strings contain only ASCII characters, use the === operator to check if they are equal. When strings contain characters that include blended characters, it first normalizes them before comparing them for equality.
How do you find a common string?
Longest common substring | DP-29
- Examples:
- Getting closer:
- A simple solution is to consider all the substrings of the first string one by one and for each substring check if it is a substring in the second string.
- Dynamic programming can be used to find the longest common substring in O(m*n) time.
- Time complexity: O(m*n)
How do you compare two characters for a string in Python?
Python comparison operators
- == : This checks if two strings are equal.
- !=
- < : This checks if the string to its left is smaller than the string to its right.
- <= : This checks if the string to its left is less than or equal to the string to its right.
- > : This checks if the string to its left is greater than the string to its right.
How do you remove common characters from two strings?
First use the nested loop and create a string with all common characters and then replace the common characters of the given strings with a blank.

How to check if two strings are equal or not?
Program to check if two strings are equal or not. Given two strings, the task is to check whether these two strings are identical (same) or not. Examples: Input: string1 = “GeeksforGeeks”, string2 = “GeeksforGeeks”. Exit: Yes.
How to count common characters in two strings?
Approach: Count the frequencies of all the characters in both strings. Now, for each character, if the frequency of this character in string s1 is freq1 and in string s2 it is freq2, the total number of valid pairs with this character will be min(freq1, freq2). The sum of this value for all characters is the required response. Attention reader!
How to compare two strings in a C program?
If the lengths of two strings are equal, only we can compare the strings. Compare each element of string s1 with each element of string s2 as follows. If the element of string s1 is equal to the element of string s2, increase the value of c by 1. Repeat this step until the last character of s2 is null.
How to compare two strings lexicographically in Java?
The compareTo() method is used to lexicographically compare two strings in Java. Each character in both strings is converted to a Unicode value for comparison. Returns the following values: if (string1 > string2) returns a positive value. i.e. (string1 == string2) returns 0.
