Detect Capital in a given string using C++
Let's suppose we have a string ‘str’ which consists of some character in it. The task is to check whether the given string has all its characters capitalized or not and return True or False respectively. For example, Input-1 −str = “INDIA”Output −TrueExplanation − Since all the character of the input string is capital, we will return true in this case.Input-2 −str = “Programmer”Output −FalseExplanation − Since all the characters of the input string are not in the capital except the first letter, we will return false in this case.The approach used to solve this problemIn the given string, we ...
Read MoreC++ Program to Delete the First Node in a given Singly Linked List
A linked list is a linear data structure that has multiple nodes that are connected with each other. Each node consists of two fields – Data Field and the address of the next node.Let us assume we have a singly linked list and we need to delete the first node from this linked list. For example, Input 1 − 4 → 3 → 2 → 1Output − 3 → 2 → 1 →Explanation − ‘4’ is the first node in the given singly linked list. After deleting the first node, the linked list will be 3→2→1.Input 2 − 1 → ...

Read MoreHow to remove repeated column names in a data.table object in R?
In data analysis, we sometimes deal with duplicated data or just the representation of the data with same name. One such situation is column names are same for two columns in a data.table object. For this purpose, we can make use of which function with the combination of duplicated function and set the output of that duplicate to NULL to remove the repeated column names.Example1Loading data.table package and creating a data.table object −library(data.table) x1
Read MoreMaximum Erasure Value in C++
Given an array of positive integers, the task is to erase a subarray containing all the unique elements. What you get by erasing the subarray is equal to the sum of its elements.Return the maximum sum of the current subarray by erasing the terms before or after it, we can get the maximum sum by erasing exactly one subarray.An array arr is called to be a subarray of a if it forms a contiguous subsequence of a that is if it is equal to a[l], a[l+1], ..., a[r] for some (l, r). For example, Input-1 −arr[ ] = { 1, 2, ...
Read MoreCount of number of given string in 2D character array in C++
The following problem is an example of daily newspaper crossword, here we are given a 2-Dimensional character array and the problem statement is to find out the given word from the 2-Dimensional character array maze.The search algorithm includes finding the individual characters from Top-to-Bottom, Right-to-Left and vice-versa but not diagonally.Let us understand with examplesInput- String word-LAYS2D String[ ] - { "LOAPYS", "KAYSOT", "LAYSST", "MLVAYS", "LAYSAA", "LAOYLS" };Output- Count of number of given strings in 2D character array: 7Explanation - As we are given with the string array of words and from them, we have to find the word “LAYS” which can ...
Read MoreCount Occurrences of Anagrams in C++
We are given an input as a text stream and a word, and the task is to find out the count of occurrences of anagrams of the word in the given text stream. Anagrams are generated by rearranging letters from a word which ends up being a different word or phrase like anagrams of words in a statement "New York Times" can be formed as "Monkeys write".For ExampleInput: String string-: “workitwrokoffowkr” word = “work” Output: Count of occurrences of anagram in the string are: 3Explanation: The possible anagrams for the word “work” are work, wrok, rowk, owkr, etc. In the ...
Read MoreCount Strictly Increasing Subarrays in C++
We are given an array containing integer elements and the task is to firstly calculate the subarray out of the given array and then check whether the elements in a subarray are in increasing order or not. If yes, then we will consider the subarray else it will be discarded.The approach here is to stop further checking the subarray if the elements in 0th and 1th position are not in increasing order.For Example- in C++Input: int a[] = {1, 7, 5}Output: Count of strictly increasing subarrays is 1Explanation - The possible subarrays include {1, 7, 5}, {1, 7}, {7, 5} where ...
Read MoreCount numbers (smaller than or equal to N) with given digit sum in C++
Given a string str containing a number and a sum total as input. The goal is to find numbers upto str that have sum of digits equal to total.Let us understand with examples.For ExampleInput - N=”110” sum=5Output - Count of numbers smaller than or equal to N with given digit sum are: 7Explanation - The numbers upto 110 that have sum of digits equal to 5 are :-5, 14, 23, 32, 41, 50 and 104.Input - N=”1000” sum=3Output - Count of numbers smaller than or equal to N with given digit sum are: 10Explanation - The numbers upto 1000 that ...
Read MoreDivisibility by 64 with removal of bits allowed in C++ Program
In this tutorial, we are going to write a program that checks whether the given binary number is divisible by 64 or not.We have given a binary number and we can remove the bits to make it divisible by 64. After removing the bits, if the number is divisible by 64, then print Yes else No.The method that we are going to use is very simple. Let's see the steps to solve the problem.Initialize the binary number in string format.Iterate over the given binary number.Count the number of zeros.If the binary number contains more than or equal to 6 and ...
