Problem of the day for today is Longest palindromic substring: Given a string, find its longest palindromic substring.. For example, given the string “ababab”, the longest palindromic substring would be “ababa”.﻿

Another interesting problem that I saw today: Given two sorted arrays, find their combined median (median of the array formed by merging both the arrays). If the number of elements in the combined array is even, then the average of the two middle elements…﻿

So here’s an interesting problem: Given an NxM integer matrix in which each row is sorted, find the overall median of the matrix assuming N*M is odd. For example,﻿

In the previous post, we talked about general game playing. Now let’s build a simple general game player, using the algorithms that we’ve already seen (Iterative deepening DFS and Iterative Deepening Alpha Beta Search).﻿

So far, we’ve talked about designing agents for specific single player and two-player zero-sum games, using heuristics to guide the search, and saw how we can model and tackle uncertainty in move generation. It’s finally time to discuss General Game…﻿
