Given two strings, str1 and str2, the task is to print the indices(Consider, indices starting from 0) of occurrence of str2 in str1. If no such index occurs, print “NONE”.
Input : GeeksforGeeks Geeks Output : 0 8 Input : GFG g Output : NONE
A simple solution is to check all substrings of given string one by one. If a substring matches, print its index.
Time Complexity : O(n * n)
An efficient solution is to KMP string matching algorithm.
- Find the starting indices of the substrings in string (S) which is made by concatenating all words from a list(L)
- Rearrange given string to maximize the occurrence of string t
- Arrange a binary string to get maximum value within a range of indices
- Program to count occurrence of a given character in a string
- Count occurrence of a given character in a string using Stream API in Java
- Minimize the length of string by removing occurrence of only one character
- Generate two output strings depending upon occurrence of character in input string.
- Generate two output strings depending upon occurrence of character in input string in Python
- Find the occurrence of the given binary pattern in the binary representation of the array elements
- Find the longest sub-string which is prefix, suffix and also present inside the string | Set 2
- Find the longest sub-string which is prefix, suffix and also present inside the string
- String Range Queries to find the number of subsets equal to a given String
- Find the character in first string that is present at minimum index in second string
- Find the count of palindromic sub-string of a string in its sorted form
- Given a string and an integer k, find the kth sub-string when all the sub-strings are sorted according to the given condition
