Ceiling And Floor In Sorted Array

Write efficient functions to find floor and ceiling of x.

Ceiling and floor in sorted array. Given a sorted array arr of size n without duplicates and given a value x find the floor of x in given array. Given a sorted array and a value x the ceiling of x is the smallest element in array greater than or equal to x and the floor is the greatest element smaller than or equal to x. Floor of x is defined as the largest element k in arr such that k is smaller than or equal to x. Let inputarray be the given sorted array of size n.

Assume than the array is sorted in non decreasing order. More precisely for a number x floor x is the largest integer less than or equal to x and ceiling x is the smallest integer. Floor of 12 is 11. Write efficient functions to find floor and ceiling of x.

First line of input contains number of testcases t. Ceiling in a sorted array. Write efficient functions to find floor of x. In this tutorial we will find the ceiling in a sorted array in c here we will have an array and a number y and we have to get ceiling of the number.

Assume than the array is sorted in non decreasing order. Given a sorted array of integers find floor and ceil of a given number in it. O lgn solution using modified binary search. Include stdio h this function returns the index of floor of k in sorted array int getfloorindex int array int left int right int k int mid.

Given a sorted array and a value x the ceiling of x is the smallest element in array greater than or equal to x and the floor is the greatest element smaller than or equal to x. Given a sorted array and a value x the floor of x is the largest element in array smaller than or equal to x. Assume than the array is sorted in non decreasing order. Given a sorted array and a value x the ceiling of x is the smallest element in array greater than or equal to x and the floor is the greatest element smaller than or equal to x.

Given a sorted array and a value x the ceiling of x is the smallest element in array greater than or equal to x and the floor is the greatest element smaller than or equal to x. Assume than the array is sorted in non decreasing order. If k is smaller that smallest element of array then no floor element. The floor and ceil map the given number to the largest previous or the smallest following integer respectively.

Moreover the ceiling of y is the smallest element in the array that is greater than or equal to y and the floor is the greatest element that is smaller than or equal to y. Arr 1 2 8. Write efficient functions to find floor and ceiling of x.
