0-1 Knapsack Problem Dynamic Programming

In this tutorial we will be learning about 0-1 Knapsack problem. In this dynamic programming problem we have n items each with an associated weight and value (benefit or profit). The objective is to fill the knapsack with items such that we have a maximum profit without crossing the weight limit of the knapsack. Since this is a 0-1 knapsack problem hence we can either take an entire item or reject it completely. We can not break an item and fill the knapsack.

Activity Selection Problem Greedy Algorithm

In this video we will learn about Activity Selection Problem, a greedy way to find the maximum number of activities a person or machine can perform, assuming that the person or machine involved can only work on a single activity at a time.

Bellman Ford Algorithm Graph

Bellman Ford algorithm is used to find the shortest paths from a source vertex to all other vertices of a given weighted directed graph. This algorithm will work well even if the graph has a negative weight edge.

Breadth First Search Graph

In this tutorial we are learning about Breadth First Search (BFS) for a graph. The graph can be both a directed graph and a non directed graph and can also contain cycles.

Bubble Sort Sorting Algorithm

Sorting Algorithm - Bubble sort - step by step guide

Bucket Sort Sorting Algorithm

In this tutorial we will be learning about Bucket sort algorithm. In this sorting algorithm we create buckets and put elements into them. Then we apply some sorting algorithm (Insertion Sort) to sort the elements in each bucket. Finally we take the elements out and join them to get the sorted result.

Calendar Aptitude

In calendar problems the question will ask us to find the name of the day for any given date. So, in order to solve the question we have to find whether the given year is a leap year or an ordinary year, we have to find the number of odd days and so on.

Chain Rule Aptitude
