Here we will see the bisect in Python. The bisect is used for binary search. The binary search technique is used to find elements in sorted list. The bisect is one library function.We will see three different task using bisect in Python.Finding first occurrence of an elementThe bisect.bisect_left(a, x, lo = 0, hi = len(a)) this function is used to return the left most insertion point of x in a sorted list. Last two parameters are optional in this case. These two are used to search in sublist.Examplefrom bisect import bisect_left def BinSearch(a, x): i = bisect_left(a, x) ... Read More
Number link is a type of logic puzzle involving finding paths to connect numbers in a grid.A simple example of a Numberlink puzzle The solution to the Numberlink puzzleRules − The player has to pair up all the matching numbers on the grid with single continuous lines (or paths). The lines cannot branch off or cross over each other, and the numbers have to fall at the end of each line (i.e., not in the middle). It is considered that a problem is well-designed only if it has a unique solution and all the cells in the grid are filled, ... Read More
A BST or binary search tree is a form of binary tree that has all left nodes smaller and all right nodes greater than the root value. For this problem, we will take a binary tree and add all the values greater than the current node to it. the problem “ add all greater values to every node in BST” is simplified as for a BST add all the node values that are greater than the current node value to that node value.Add all greater values to each node in the BST Problem Statement:Given a Binary Search Tree (BST), we ...

Float is a shortened term for "floating-point." By definition, it's a fundamental data type built into the compiler that's used to define numeric values with floating decimal points. A floating-point type variable is a variable that can hold a real number, such as 4320.0, -3.33, or 0.01226. The floating part of the name floating point refers to the fact that the decimal point can “float”; that is, it can support a variable number of digits before and after the decimal point.floating pointCategoryTypeMinimum SizeTypical Sizefloating pointfloat4 bytes4 bytesdouble8 bytes8 byteslong double8 bytes8, 12, or 16 bytesFloating-point rangeSizeRangePrecision4 bytes±1.18 x 10-38 to ...

The format is a string that is printed in the output screen. And the … is the ... Read More
The concept of finding the sum of sum of integers is found such that first, we will find the sum of numbers up to n and then add all the sums to get a value which will be the sum of sum which is our desired sum.For this problem, we are given a number n up to which we have to find the sum of the sum. Let's take an example to find this sum.n = 4Now we will find the sum of numbers for every number from 1 to 4 :Sum of numbers till 1 = 1 Sum of ... Read More
