In below C++ code ordered hashmap is used where the time complexity of insert and search is O(Logn). Time Complexity: O(n2), because we have to go through the entire string for all possible different starting points in order to generate all the substrings. O(1), no extra space is required, so it is a constant.

Count number of Distinct Substring in a String - GeeksforGeeks For string ababa, lcp array is [1, 3, 0, 2, 0]After constructing both arrays, we calculate total number of distinct substring by keeping this fact in mind : If we look through the prefixes of each suffix of a string, we cover all substrings of that string. Total Count of the distinct substrings is 9 + 1 (for empty string) = 10. Number of Distinct Substrings in a String 1698.

Count the number of set bits in a 32-bit integer, Count the number of occurrences of a character in a string in Javascript. Total number of nodes is 10 which is our answer. For every sub-string check if it is present in dp array (i.e dp[i][j] == true) and print it. This article is contributed by Utkarsh Trivedi. Return the number of distinct substrings of size 2 that appear in s as contiguous substrings. Step 3: Printing the distinct palindromes and number of such distinct palindromes:The last step is to print all values stored in the HashMap (only distinct elements will be hashed due to the property of HashMap).
