I am trying to get better understanding of Tarjan's algorithm for finding SCC, articulation points and bridges. I am considering a special case where the graph
I'm currently learning as much as I can about recursion but I'm really stuck on how to use it to check whether all the number elements in an array are even numb
I have the following interview question that may require traversing through the entire string. Problem I searched about find Problem and most
I am trying to implement an efficient precomputed culling scheme in my 3D city model viewer program (a user can upload a 3D model of a city from any number of a
I have this code that works perfectly but in the opposite direction ( left ) I would like to rotate this array to the right, how can I do this? public int[] Ro
Question: If a graph contains no negative-weight cycles, does there exist an ordering of edges such that Bellman-Ford computes shortest paths by relaxing each e
Faced this question in an interview, which basically stated Find if the given two strings are anagrams of each other in O(N) time without any extra space I tr
I need to generate (iterator) a random sequence of 32 bit integers with absolutely no repeats. The naive solutions to this problem don't work for me because of
Given lots of intervals [ai, bi], find the interval that contains the most number of intervals. I easily know how to do this in O(n^2) but I must do it in O(nlo
This code is currently showing the total amount needed to reach the next level, but what I would like it to do is show the complete total amount so for example

My assignment: Consider two arrays a and b where each consists of n integers. In one operation: Select two indices i and j (0 <= i,j < n) Swap integers a
Given an array having n elements, find all the possible pairs of elements whose product is between x and y provided by the user, i.e. all i and j less than n, s
