Given a string str, the task is to check whether the string contains two non-overlapping sub-strings s1 = “geek” and s2 = “keeg” such that s2 starts after s1 ends.
Input: str = “geekeekeeg”
“geek” and “keeg” both are present in the
given string without overlapping.
Input: str = “geekeeg”
“geek” and “keeg” both are present but they overlap.
Approach: Check if the sub-string “geek” occurs before “keeg” in the given string. This problem is simpler when we use a predefined function strstr in order to find the occurrence of a sub-string in the given string.
Below is the implementation of the above approach:
- Count of non-overlapping sub-strings "101" and "010" in the given binary string
- Count pairs of non-overlapping palindromic sub-strings of the given string
- Number of substrings of a string
- Replace two substrings (of a string) with each other
- Check whether all the substrings have number of vowels atleast as that of consonants
- Split the string into substrings using delimiter
- Different substrings in a string that start and end with given strings
- Number of even substrings in a string of digits
- Program to print all substrings of a given string
- Count of substrings of a binary string containing K ones
- Sum of all substrings of a string representing a number | Set 1
- Lexicographical concatenation of all substrings of a string
- Number of substrings of one string present in other
- Number of substrings with odd decimal value in a binary string
- Number of substrings divisible by 6 in a string of integers
