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 ... Read More

binary search, also known as half-interval search, logarithmic search, or binary chop, is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array. If they are not equal, the half in which ... Read More

Fibonacci series is a mathematical sequence of number which starts from 0 and the sum of two numbers is equal to the next upcoming number, for example, the first number is 0 and the second number is 1 sum of 0 and 1 will be 1F0=0, F1=1AndFn=Fn-1+Fn-2, F2=F0+F1 F2=0+1 F2=1then ... Read More

A string is an array of characters. In this problem, we are given a string which has opening and closing brackets. And we will balance this string by removing extra brackets from the string.Let’s take an example, Input : “)Tutor)ials(p(oin)t(...)” Output : “Tutorials(p(oin)t(...))”To solve this problem, we will traverse through ...

The average of number in a stream means calculating the average after every insertion. But in this problem, we need to find the average of max K numbers in a stream i.e. only k numbers of the array are considered for calculating the average. When we add a number if ... Read More

Average of numbers is the sum of numbers divided by the total number of numbers.In this problem, we are given a stream of numbers. And we will print average of the number at every point.Let’s take an example of how it works −We have a stream of 5 number 24 ... Read More

In c++ programming language, an associative array is a special type of array in which the index value can be of any data type i.e. it can be char, float, string, etc. These associative arrays are also known as maps or dictionaries. Also, the indexes are given a different name ... Read More

The integer is a data type used to define a number that contains all positive, negative or zero non-fractional values. These cannot have decimals.Float is a data type used to define a number that has a fractional value. These can have decimals also.Now, we will check what will be the ... Read More
