Maximum Weight Difference in C++
In this problem, we are given an array arr[] and a number M. Our task is to create a program to calculate the Maximum Weight Difference in C++.Problem StatementWe will find M elements from the array such that the absolute difference between the sum and the sum of rest elements is maximum.Let’s take an example to understand the problem, Input: arr[] = {3, 1, 6, 9, 4} M = 3Ouput:15ExplanationWe will consider 4, 6, 9. The sum is 19. The absolute difference with the sum of rest numbers is|19 - 4| = 15Solution ApproachThe solution to the problem is based ...
Read MoreMaximum value with the choice of either dividing or considering as it is in C++
In this tutorial, we will be discussing a program to find maximum value with the choice of either dividing or considering as it is.For this we will be provided with an integer value. Our task is to find the maximum value with either by dividing the number into four parts recursively or choosing it as it is using the given function F(n) = max( (F(n/2) + F(n/3) + F(n/4) + F(n/5)), n).Example#include using namespace std; //calculating the maximum result int findMaximum(int size) { int term[size + 1]; term[0] = 0; term[1] = 1; int i=2; while(i
Read MoreQueries for characters in a repeated string in C++
In this problem, we are given a string str and Q queries consisting of two values a and b. Our task is to create a program to solve Queries for characters in a repeated string in C++.Problem DescriptionTo solve each query, we need to check whether the characters at index a and b are the same and return the value accordingly.Let’s take an example to understand the problem, Input: str = “tutorialspoint”Q = 2Query = {{0, 2}, {4, 7}}Output:RepeatedNot RepeatedExplanationFor Query 1, the character at index 0 is t, and the character at index 2 is t. Both are the ...
Read MoreMaximums from array when the maximum decrements after every access in C++
In this problem, we are given an array arr[]and an integer M. Our task is to create a program to find Maximums from array when the maximum decrements after every access in C++.Problem DescriptionTo find the maximum, we will find the maximum element from the array and after every retrieval and decrease it by -1, M times.Let’s take an example to understand the problem, Input: arr[] = {3, 6, 8, 9} M = 2Ouput:17Explanation1st iteration, maximum = 9, sum = 9, updated arr = {3, 6, 8, 8}2nd iteration, maximum = 8, sum = 9+8 = 17, updated arr = ...
Read MoreQueries for counts of multiples in an array in C++
In this problem, we are given an arr[] and Q queries each consisting of a value m. Our task is to create a program to solve the Queries for counts of multiples in an array in C++.Problem DescriptionFor solving the queries, we need to count all the numbers that are multiples of m. For this we will check for elements divisible by m.Let’s take an example to understand the problem, Input:arr[] = {4, 7, 3, 8, 12, 15}Q = 3 query[] = {2, 3, 5}Ouput:3 3 1ExplanationQuery 1: m = 2, multiples in the array = 4, 8, 12. Count ...
Read MoreQueries for counts of array elements with values in given range in C++
In this problem, we are given an array arr[] and Q queries, each can be one of the two types, {1, L, R}− For the count of array elements in the range [L, R].{2, index, val}− For updating the element at index with val.Our task is to create a program to solve the Queries for counts of array elements with values in given range in C++.Let’s take an example to understand the problem, Input:arr[] = {1, 5, 2, 4, 2, 2, 3, 1, 3}Q = 3Query = { {1, 4, 8}, {2, 6, 5}, {1, 1, 4}}Ouput:3 7ExplanationQuery 1: count ...
Read MoreQueries for maximum difference between prime numbers in given ranges in C++
In this problem, we are given Q queries that consist of two values L and R. Our task is to create a program to solve Queries for maximum difference between prime numbers in given ranges in C++.Problem description: Here, in each querry, we are given two values L and R. We have to find the maximum difference i.e. the difference between the largest and the smallest prime numbers within the given range.Let’s take an example to understand the problem, InputQ = 2 2 45 14 16 41 0OutputExplanationFor query 1, the smallest prime number within the given range is 2 ...
Read MoreQueries for decimal values of subarrays of a binary array in C++
In this problem, we are given a binary array bin[] and Q queries each consists of two values L and R. Our task is to create a program to solve queries for decimal values of subarrays of a binary array in C++.Problem description − Here to solve each query, we will have to find and print the decimal number which is created by the subarray starting from L to R i.e. subarray[L...R].Let’s take an example to understand the problem, Inputbin[] = {1, 1, 0, 0, 1, 0, 1, 0, 0, 0} Q = 2 2 5 0 6Output2 101ExplanationFor query ...
Read MoreQueries for frequencies of characters in substrings in C++
In this problem, we are given a string. And Q queries each has two integers l and r and character ch. our task is to create a program to solve the queries for frequencies of characters in substrings in C++.Problem description: Here for each querry, we will find the frequency of occurrence of the character ‘ch’ in the substring str[l...r].Let’s take an example to understand the problem, Inputstr = “tutorialspoint” Q = 2 0 6 t 5 13 iOutput2 2ExplanationFor query 1 − the substring is “tutoria”, the character t appears 2 times.For query 2 − the substring is “ialspoint”, ...
Read MoreWrite a C program that displays contents of a given file like 'more' utility in Linux
Here, we will write a C program that will display the contents of a file page by page as displayed in Linux using the more command.This program will show a specific number of lines on the screen first and then wait for the user to hit enter to move to the next page i.e. next set of n lines.For displaying the content of the file like this we will open the file and print its contents. And maintain a counter for new lines in the file. When this counter reaches n, we will read a key pressed by the user ...
