XNOR(Exclusive-NOR) gate is a digital logic gate that takes two inputs and gives one output. Its function is the logical complement of the Exclusive-OR (XOR) gate. The output is TRUE if both inputs are the same and FALSE if the inputs are different. The truth table of the XNOR gate is given below. A B Output 1 1 1 1 0 0 0 1 0 0 0 1 Problem Statement Given two numbers x and y. Find the XNOR of the two numbers. Sample Example 1 Input: x ... Read More

Quick Sort is a Divide and Conquer algorithm. In this algorithm, we elect a pivot element and then partition the array around the pivot element. The two partitions are such that one part contains elements all lower than the pivot element and the other part contains elements all higher than the pivot element. Similarly, each part is further partitioned around a pivot selected in each part and this process is executed until one single element is reached. Choosing a Pivot A pivot can be chosen in an array as follows − A random pivot. Rightmost or leftmost element as ... Read More

Tarjan’s algorithm is to locate strongly linked components in a directed graph, Robert Tarjan created the graph traversal technique known as Tarjan's algorithm in 1972. Without going over previously processed nodes, it effectively locates and handles each highly related component using a depth-first search strategy and a stack data structure. The algorithm is often employed in computer science and graph theory and has several uses, including algorithm creation, network analysis, and data mining. Kosaraju’s algorithm consists of two passes over the graph. In the first pass, the graph is traversed in reverse order and a "finish time" is assigned ... Read More

GeoPandas, a widely used Python library build on top of the Pandas library to include the support of geospatial data. Here, geospatial data or geodata describes the information related to the various locations on Earth's surface. These datasets have many use cases including visualization of maps, urban planning, analysis of trade locations, network planning and so forth. In this article, we are going to explore how the GeoPandas library works and also, how to plot geospatial data using GeoPandas. Plotting Geospatial data using GeoPandas in Python Since GeoPandas extends the features of the Pandas library, we need to ... Read More
