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.
- Check if a string can be split into even length palindromic substrings
- Remove minimum characters from string to split it into three substrings under given constraints
- Check if a string can be split into two strings with same number of K-frequent characters
- Split the string into substrings using delimiter
- 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 ways to split a Binary String into three substrings having equal count of zeros
- Check if given string can be split into four distinct strings
- Find the starting indices of the substrings in string (S) which is made by concatenating all words from a list(L)
- Minimum number of substrings the given string can be splitted into that satisfy the given conditions
- Check if an array can be split into 3 subsequences of equal sum or not
- Substrings starting with vowel and ending with consonants and vice versa
- Check If every group of a's is followed by a group of b's of same length
- Count of ungrouped characters after dividing a string into K groups of distinct characters
- Decode a string recursively encoded as count followed by substring
- Rearrange a string in sorted order followed by the integer sum
- Rearrange a string in the form of integer sum followed by the minimized character
- String formed with middle character of every right substring followed by left sequentially
- Count of Substrings that can be formed without using the given list of Characters
- Check if a Palindromic String can be formed by concatenating Substrings of two given Strings
Below is the implementation of the above approach:
Time Complexity: O(N)
Auxiliary Space: O(1)
