Given a string str, the task is to check if it can be split into substrings such that each substring starts with a numeric value followed by a number of characters represented by that numeric integer.
Input: str = “4g12y6hunter”
Substrings “4g12y” and “6hunter” satisfy the given condition
Input: str = “31ba2a”
The entire string cannot be split into substrings of desired types
Follow the steps below to solve the problem:
- Check for the conditions when a split is not possible:
- If the given string does not start with a number.
- If the integer, in the beginning of a substring, is greater than the total number of succeeding characters in the remaining substring.
- If the above two condition are not satisfied, an answer is definitely possible. Hence find the substrings recursively.
- Remove minimum characters from string to split it into three substrings under given constraints
- Check if a string can be split into even length palindromic substrings
- Check if a string can be split into two strings with same number of K-frequent characters
- Split the string into substrings using delimiter
- Find the starting indices of the substrings in string (S) which is made by concatenating all words from a list(L)
- Split the binary string into substrings with equal number of 0s and 1s
- Split a given string into substrings of length K with equal sum of ASCII values
- Count of substrings of a given Binary string with all characters same
- Count number of substrings of a string consisting of same characters
- Calculate Sum of ratio of special characters to length of substrings of the given string
- Check if given string can be split into four distinct strings
- Check if a Palindromic String can be formed by concatenating Substrings of two given Strings
- Find distinct characters in distinct substrings of a string
- Substrings starting with vowel and ending with consonants and vice versa
- Check whether second string can be formed from characters of first string
- Check if both halves of the string have same set of characters
- Quick way to check if all the characters of a string are same
- Check if characters of one string can be swapped to form other
- Check if both halves of the string have same set of characters in Python
- Check if the characters of a given string are in alphabetical order
Below is the implementation of the above approach:
Time Complexity: O(N)
Auxiliary Space: O(1)
