Count Binary Substrings - LeetCode
WebDec 15, 2024 · Here base condition comes out to be i>j if we hit this condition, return 1. 2. We check for each and every i and j, if the characters are equal, if that is not the case, return 0. 3. Call the is_palindrome function again with incremented i and decremented j. 4. Check this for all values of i and j by applying 2 for loops. WebMay 18, 2024 · Naive Approach: Generate all substring of size K.; Find maximum of count of set bits in all substrings. Time Complexity: O( N 2). Auxiliary Space: O(1). Efficient Approach: The problem can be solved using Sliding window technique. Take maxcount variable to store maximum count of set bit and Count variable to store count set bit of … WebFeb 17, 2024 · Method 1 (Brute Force): If the length of string is n, then there can be n* (n+1)/2 possible substrings. A simple way is to generate all the substring and check each one whether it has exactly k unique characters or not. If we apply this brute force, it would take O (n*n) to generate all substrings and O (n) to do a check on each one. riding on 2 different tires suv
