Given a string str, the task is to count all possible sub-strings of the given string that are prefix of the same string.
Input: str = “ababc”
All possible sub-string are “a”, “ab”, “aba”, “abab”, “ababc”, “a” and “ab”
Input: str = “abdabc”
Approach: Traverse the string character by character, if the current character is equal to the first character of the string then count all possible sub-strings starting from here that are also the prefixes of str and add it to count. After the complete string has been traversed, print the count.
Below is the implementation of the above approach:
- Python program to print the substrings that are prefix of the given string
- Find the longest sub-string which is prefix, suffix and also present inside the string
- Print the longest prefix of the given string which is also the suffix of the same string
- Longest string in an array which matches with prefix of the given string
- Replace two substrings (of a string) with each other
- Number of substrings of a string
- Number of substrings of one string present in other
- Count of substrings of a binary string containing K ones
- Lexicographical concatenation of all substrings of a string
- Split the string into substrings using delimiter
- Program to print all substrings of a given string
- Number of even substrings in a string of digits
- Different substrings in a string that start and end with given strings
- Sum of all substrings of a string representing a number | Set 1
- String from prefix and suffix of given two strings
