A programming language defines a set of instructions that are compiled together to perform a specific task by the CPU (Central Processing Unit). The programming language mainly refers to high-level languages such as C, C++, Pascal, Ada, COBOL, etc. ...
I designed a solution purely based on recursion - public static boolean isKPalindrome(String str, int k) { if(str.length() < 2) { return true; } if(str.charAt(0) == str.charAt(str.length()-1)) { return isKPalindrome(str.substring(1, str.length()-1), k); } else{ if(k...
Q: Implement an algorithm to check if a linked list is a palindrome. Q: Implement a 'Hash table'. Stacks and Queues A stack is a data structure which contains a list of elements with LIFO (last in first out) ordering. The most recent item added (push()ed) to the stack is the fir...

define dp(a, b) to be the number of paths from cell a to cell b that are a palindrome (a is above and to the left of b). There are four transitions: cell a can move down or right while cell b can move up or left, and add these up. Our answer is dp(top left cell, botto...
