In details explain(the idea in pseudocode) and implement (in java) the following problem: Given a target value and a sorted array, assuming no duplicates in that array, if the target is found in the array, return its index. If not, return where it should be inserted(why it should be inserted there). Give a O(log n) time algorithm.
Example: {2,5,8,10}, target=5, returns 1. {2,5,8,10}, target=6, returns 2.
//Binarysearch.java import java.util.Scanner; public class BinarySearch { private static int binarySearch(int[] input, int low, int high, int key) { int mid; if(low<=high){ mid = (low+high)/2; if(input[mid] == key){ return mid; } else if(input[mid] < key){ return binarySearch(input,mid+1,high,key); } else{ return binarySearch(input,low,mid-1,key); } } return -1; } public static void main(String[] args) { int arr[] = {2,5,8,10}; System.out.println(binarySearch(arr,0,arr.length-1,5)); int arr2[] = {2,5,8,10}; System.out.println(binarySearch(arr2,0,arr.length-1,6)); } }

the programming language is in java Problem 2 You are given an array A with n distinct elements. Implement an (n log n)-time algorithm that creates an array B where all elements are in range from 0 to n - 1 and where the order of elements is the same as in A. That is, 0 has the same index in B as the smallest element in A, 1 has the same index in B as the second smallest element...
Subject: Algorithm need this urgent please thank you. 4. Give pseudocode for an algorithm that will solve the following problem. Given an array A[1..n) that contains every number between 1 and n +1 in order, except that one of the numbers is missing. Find the miss sorted ing mber. Your algorithm should run in time (log n). (Hint: Modify Binary search). A pseudocode means an algorithm with if statements and loops, etc. Don't just write a paragraph. Also, if your...
Please answer this in python pseudocode. It's an algorithm question. 1. [10 marks] Consider the function SumKSmallest(A[0..n – 1), k) that returns the sum of the k smallest elements in an unsorted integer array A of size n. For example, given the array A=[6,-6,3,2,1,2,0,4,3,5] and k=3, the function should return -5. a. [3 marks) Write an algorithm in pseudocode for SumKSmallest using the brute force paradigm. Indicate and justify (within a few sentences) the time complexity of your algorithm. b....
IN JAVA please Given a sorted array and a target value, return the index if the target is found. If not, return the index where it would be if it were inserted in order. Your code will be tested for runtime. Code which does not output a result in logarithmic time (making roughly log(2) N comparisons) will fail the tests. A sample main function is provided so that you may test your code on sample inputs. For testing purposes, the...
1. Please write a Divide-and-Conquer Java algorithm solving the following problem: Given an "almost sorted" array of distinct integers, and an integer x, return the index of x in the array. If the element x is not present in the array, return -1. "Almost sorted" means the following. Assume you had a sorted array A[0…N], and then split it into two pieces A[0…M] and A[M+1…N], and move the second piece upfront to get the following: A[M+1]…A[N]A[0]…A[M]. Thus, the "almost sorted"...
PLEASE IMPLEMENT YOUR SOLUTION RECURSIVELY IN C++. IT WOULD BE GREAT IF YOU COULD ALSO PROVIDE TEST CODE FOR IT. 5) Design a recursive function to find the immediate successor of a target integer in an array o:f sorted integers. Here the immediate successor of a target is defined as the smallest number that is no smaller than the target in this sorted array int binarySuccessor(const int anArrayl, const int first, const int last, int target); In the above function...
2. The following (adapted from Wikipedia) gives pseudocode for searching a sorted vector A for a specific element T. Given an array A of n elements with values or records A1 An and target value T, the following subroutine uses binary search to find the index of T in A. 1. Set L to 1 and R ton. 2. If L>R, the search terminates as unsuccessful Set m (the position of the middle element) to the floor of (L+R)/2. 3....
Consider the following problem: Input: a list of n-1 integers and these integers are in the range of 1 to n. There are no duplicates in list. One of the integers from 1 to n is missing in the list. Output: find the missing integer Let the input array be [2, 4, 1, 6, 3, 7, 8]. Elements in this list are in the range of 1 to 8. There are no duplicates, and 5 is missing. Your algorithm needs...
please I need it urgent thanks algorithms 2.1 Searching and Sorting- 5 points each 3. What is the worst case for quick sort? What is the worst case time com- plexity for quick sort and why? Explain what modifications we can make to quick sort to make it run faster, and why this helps. 4. Give pseudocode for an algorithm that will solve the following problem. Given an array AlL..n) that contains every number between 1 and n +1 in...
Stacks and Java 1. Using Java design and implement a stack on an array. Implement the following operations: push, pop, top, size, isEmpty. Make sure that your program checks whether the stack is full in the push operation, and whether the stack is empty in the pop operation. None of the built-in classes/methods/functions of Java can be used and must be user implemented. Practical application 1: Arithmetic operations. (a) Design an algorithm that takes a string, which represents an arithmetic...
