In the field of data structure, a range query is a pre-processing method to operate on some input data in an efficient manner. A range query is responsible to answer any query of the particular input on any data subset. If we want to copy some data columns from a table we need to maintain an index for that particular dataset. An index is a direct link or a key, which is designed to provide an efficient searching process in a data set. It is mainly used to speed up the data retrieving from a lost data source. In mathematics, ... Read More

Ranging a query is a common database current interest operation present in data structure to restore all the records where the output value lies between an upper and lower boundary. This process works with some input data, to structure them in an efficient manner on any subset of a particular input. The range function, denoted as range() is used to iterate a for loop over a series. We need to declare the start as 0 at the beginning of a process. If somehow we miss this step, the process will run and iterate the loop until the end (-1). A ... Read More

Array is a set of a single non primitive similar data types (values or variables) that stores the elements in a memory with a fixed number of values. After creating an array with certain elements, the length of this data set became fixed. Here non primitive means, these data types can be used to call a method to perform a particular operation which can be null in character. Here the bitwise sum means, sum of certain numbers with an exactly 2 bits set. Bitwise OR denotes that each integer is present in a subarray. It is an adjacent non-void element ... Read More

A string is an object, which represents a sequence of data characters. The strings are the data container which always represented as a text format. It also used to concept, compare, split, join, replace, trim, length, intern, equals, comparison, substring operation. K largest(or smallest) elements in an array using Quick Sort partitioning algorithm. Here is an array R[] with N number of distinct integers. The task is to find that particular element which are strictly greater than all the elements preceding it and strictly greater than at least K elements on its right. The problem states that an array ... Read More

In this article, we will learn how to count inversions of size three in a given array. The goal is to find how many triplets (i, j, k) exist such that i < j < k and arr[i] > arr[j] > arr[k].Understanding Inversion Count Inversion count is a step-counting method by which we can calculate the number of sorting steps taken by a particular array. It is also capable of counting the operation time for an array. But, if we want to sort an array in a reverse manner, the count will be the maximum number present in that array. Array: ... Read More

Calculating the total number of hours, days, minutes, and seconds between two dates is achievable in Golang. In this article, we'll go through how to accomplish this in Golang, along with the necessary libraries and sample code. Calculating the Total Number of Hours, Days, Minutes, and Seconds In Golang, we may utilise the time package to determine how many hours, days, minutes, and seconds are there between two dates. To modify dates and times, the time package offers a number of functions. The total number of hours, days, minutes, and seconds between two dates can be calculated in Go ... Read More

A buffered channel in Golang is a particular kind of channel that enables several values to be transmitted and received without blocking. In this post, we'll talk about buffered channels in Golang, their syntax, and some real-world uses. What is a Buffered Channel? In Golang, a channel type that can keep a predetermined number of values before blocking is known as a buffered channel. As long as there is space in the buffer, this permits sending and receiving numerous values without blocking. Any additional attempts to send data will be blocked after the buffer is filled until more room is ... Read More

The caret (^) character in Golang stands in for the bitwise NOT operator. By flipping 0s and 1s into 1s and 0s into 0s, this operator inverts the bits of an integer value. We'll talk about Golang's bitwise NOT operator and some real-world uses for it in this article. What is the Bitwise NOT Operator? The complement operator, also referred to as the bitwise NOT operator, is a unary operator that performs bit inversion on a single operand. For processing binary data in computer programmes, use this operator. The bitwise NOT operator flips all of the bits in an integer ... Read More

Bits package in Golang has functions for changing a binary number's individual bits. This package is very helpful in low-level applications like networking, cryptography, and bitwise operations. This post will go through the Golang bits package and show you how to utilise it in a real-world application. Introduction to the Bits Package The bits package offers tools for working with a binary number's constituent bits. The "BitArray" type, which represents a series of bits, is the main type in the bits package. An implementation of the "BitArray" type is a slice of "uint64" values, where each "uint64" value has ...
