int[] pre = new int[pattern.length()]; // pre[0] = 0, pre[i] means the index of prefix // index used to store the position of matched prefix int index = 0; int i = 1; while(i < pattern.length()) { if(pattern.charAt(i) == pattern.charAt(index)) { pre[i] = index +...
So we can simply scan through every char in the input string, and search to left and right for each character see if we can find a palindrome. This only takes O(1) space, and the same O(n^2) time. You can also use the length of the string and the starting char instead of the...
nextInt(); temp_num = actual_num; while(temp_num > 0){ //Store remainder rem = temp_num % 10; // Store number in reverse form rev = rev*10+rem; //Truncate last digit from number temp_num = temp_num/10; } //actual_num value and rev value matches it means //number ...
In this blog, we have to figure out a palindrome linked list. A Palindrome linked list means a Linked List which has values in a palindromic form i.e. values from left to right will be the same as the values from right to left in the linked list. Let’s discuss how to find a pal...
a) If it is available in Trie then return true b) If it is partially available Check the remaining word is palindrome or not If yes then return true that means a pair forms a palindrome. Note: Position upto which the word is palindrome ...
