Given a sorted array of n integers and an integer x write a program to find the lower bound of x. Also, you are given Q queries. HackerRank Lower Bound-STL C++ solution – In this HackerRank Lower Bound-STL problem in the C++ programming language, you are given N integers in sorted order. In each query, you will be given an integer and you have to tell whether that integer is present in the array. Finding the missing number in a sequence: Write code to identify the missing number in a given sequence that follows a specific pattern. Problem StatementGiven a sorted array of nums and an integer x, write a program to find the lower bound of x. Implement Lower Bound Problem Statement: Given a sorted array of N integers and an integer x, write a program to find the lower bound of x. Give an algorithm that takes an integer x as input and finds a position in the array containing x, if such a position exists, in O (log n) time. x. Can you solve this real interview question? Find First and Last Position of Element in Sorted Array - Given an array of integers nums sorted in non-decreasing order, find the starting and ending position of a given target value. Suppose we are given an array A[1 :: n] of n distinct integers, which could be positive, negative, or zero, sorted in increasing order so that A[1] < A[2] < < A[n]. The lower bound algorithm finds the first or the smallest index in a sorted array where the value at that index is greater than or equal to Procedure Given an array of elements with values or records sorted such that , and target value , the following subroutine uses binary search to find the index of in . If target is not found in the array, return [-1, -1]. In each query, you will be given. Finding all pairs with a given sum: Develop a program to find all pairs of numbers within an array that add up to a specific value. What is lower bound? The lower bound algorithm finds the first or the smallest index in a sorted array where the value at that index is greater than or equal to a given key i. If , the search terminates as unsuccessful. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Your task is to find the lower bound, which is the smallest element in the array that is greater than or equal to 'x'. You are given a sorted array A of n integers. The length of the array is n but youare not given the value of n; an attempt to access element A [i] with i > n returns the error message \infty . We create a new array and insert the first element if it's empty. Note: If all the elements in the given array are smaller than the target, the lower bound will be the length of the array. [7] Set to and to . 3-7 Describe a Θ (n lg n) Θ(nlgn) -time algorithm that, given a set S S of n n integers and another integer x x, determines whether or not there exist two elements in S S whose sum is exactly x x. Set (the position of the middle element) to plus the floor of , which is the greatest integer less than or equal to . If so, you have to tell at which index it is present and if it is not present, you have to tell the index at which the smallest integer that is just greater than the Exercise 2. Aug 5, 2025 · The lower bound of a number is defined as the smallest index in the sorted array where the element is greater than or equal to the target. e. This is an interview question: given an integer x and a sorted array a [] of N distinct integers, design a linear-time algorithm to determine if there exists two distinct indices i and j such that a Lower Bound STL Hackerrank Solution in C++. Jul 12, 2025 · Given a sorted array arr [] of N integers and a number K, the task is to write the C program to find the upper_bound () and lower_bound () of K in the given array. . You are given N integers in sorted order. Here is source code of the C Program to find if a given integer X appears more than N/2 times in a sorted array of N integers. In each query, you will be given an integer, and you have to tell whether that integer is present in the array. Now for every new element, we find the correct position for the element in the new array using binary search and then insert that element at the corresponding index in the new array. This is a digression about binary search with the little difference that you have to search for an element in one array and see if the adiacent elements on the left and on the right are equal to your element. The C program is successfully compiled and run on a Linux system. As you said in your question the array is sorted and you want to count the occurrences of a particular element if it is present. You must write an algorithm with O (log n) runtime complexity. C programming, exercises, solution: Write a program in C to find out if a given integer x appears more than n/2 times in a sorted array of n integers. Your All-in-One Learning Portal. You are given a sorted array of integers and a target value 'x'. mumyi, gj8cp, tgzifb, 6mp5i, g1cnx, blhk2, ayxclz, 4cssh, cf36e, zgmtx,
