Given a sorted (in ascending order) integer array nums of n elements and a target value, write a method to perform a binary search for a target value in nums. If target exists, then return its index, otherwise return -1. Analyze the running time, T(n).
public int search(int[] nums, int target) {
// YOUR CODE GOES HERE
} // end search
public int search(int[] nums, int target) {
int low = 0;
int high = nums.length - 1;
int mid;
while (high >= low) {
mid = (low + high) / 2;
if (target == nums[mid])
return mid;
else if (target > nums[mid])
low = mid + 1;
else
high = mid - 1;
}
return - 1;
}

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...
Write a C++ function binsearch that carries out the binary search algorithm on a sorted array of integers. Your function takes as parameters an array of integers (sorted in increasing order), the size of the array, and a target integer to search for. The function returns the index of the target in the array, and returns -1 if the target is not in the array. The file main1.txt on the webpage contains code that generates a specific array of integers...
c programming. Given a sorted array of 20 integers and a target integer value, your program needs to print out all pairs of integers which have sum equal to the target value. If there is no pair of integers to return, print out “No pair of integers in the given array can be summed to the target value”. The array of integers and the target value should be given from the keyboard (taken as user input). Inputs and Outputs should...
Please Write in Java An array is sorted (in ascending order) if each element of the array is less than or equal to the next element . An array of size 0 or 1 is sorted Compare the first two elements of the array ; if they are out of order, the array is not sorted; otherwise, check the if the rest of the array is sorted. Write a boolean -valued method named isSorted that accepts an integer array , and the number of...
Implement a method to build an AVL tree out of a sorted (ascending order) array of unique integers, with the fastest possible big O running time. You may implement private helper methods as necessary. If your code builds a tree that is other than an AVL tree, you will not get any credit. If your code builds an AVL tree, but is not the fastest big O implementation, you will get at most 12 points. You may use any of...
using c++ Write a function that returns true if a given integer array is sorted(in ascending order) and false if it is not. The function should perform no more than "size" comparisons. bool isSorted(int A[], int size);
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"...
In Java: In a sorted (ascending) integer array of length n with no duplicates, print all values in the range x to y. Assume both x and y are in the array. What is the worst case big O running time if there are k integers within the range?
6.) (a) A string contains several X's followed by several O's. Devise a divide-and-conquer algorithim that finds the number of X's in the string in log2n steps, where n is the length of the string. (b) An array originally contained different numbers in ascending order but may have been subsequently rotated by a few positions. For example, the resulting array may be: 21 34 55 1 2 3 4 5 8 13 Is it possible to adapt the Binary Search...
Write A JAVA mergesort method that mergesorts array elements in descending order. Write A JAVA binary search method that searches x in a sorted array with n elements and returns its position if exist, -1 otherwise.
