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.

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.

Changing Directory Unix

In Unix like operating system the files are organised in a hierarchical directory structure which is similar to a tree like structure. The first directory in this directory structure is called the root directory and it contains all the other files and subdirectories.
