True or False
For each statement below, indicate whether you think it is True or False.
- Inserting elements into a sorted array is O(n) because you have to find the location to add the new element and then shift the remaining elements
- If the sorted array gets too large, the performance of binary search becomes O(n)
- For the delete
algorithm , after you find the element to delete, you can make the algorithm run faster by replacing it with the last element in the array - If you used binary search to find the element to delete, the performance is still O(n) because you may have to shift all elements

- Homework 7: Merging two sorted arrays Due date: Saturday March 18. Objectives: Learn to implement algorithms that work with multiple arrays. Understand the Merging algorithm. IMPORTANT. Carefully study Lecture 1 from Week 8 on D2L before you start on this. Sometimes we need to combine the values in two sorted sequences to produce a larger sorted sequence. This process is called Merging. As an example, if the first sequence (S1)contains the numbers 2 3 4 4 5 9 and the second sequence (S2) contains the numbers 1 4 5 8 9 11 12 13 17 the output sequence will contain 1 2 3 4 4 4 5 5 8 9 9 11 12 13 17 Each sequence can be stored in an array. The strategy is as follows: Start by comparing the first items in the two input arrays. Write the smaller number to the output array, and move to the the next item in that array. This is repeated until we reach the end of any one of the input arrays; thereafter, we simply copy all the numbers from the other input array to the output array. (In the…Best Partition You are given an array of positive numbers of size N and an integer K. You need to partition the array into K continuous segments. For each segment, the sum of its elements needs to be calculated. The segment with the minimum sum is called the bestSegment and the sum of the elements of the bestSegment is called the bestSum. For all possible combinations of partitions of the array when divided into K segments, their bestSum needs to be calculated and the one among them with maximum value needs to be returned. Input Specification: input1: an array of N positive numbers input2: an integer N denoting the length of the array input3: an integer K Output Specification: Return an integer denoting the maximum value of all possible bestSum. Example 1: input1: (1,2,3,4} input2: 4 input3: 2 Output: 4 Explanation: You can partition the given array into 2 continuous segments in the following manner- • 123 14- the sum of individual segments is (6,4) and the bestSum is 4 • 12134- the…Question 8 Sort the following numbers using an "in place" version of a selection sort. This means that you should have only one array throughout and all elements should be present at all times. Show each "pass" of the algorithm. 34, 25, 11, 44, 21, 8, 4, 28, 16, 31
- True or False For each statement below, indicate whether you think it is True or False If you have an array with no “holes”, the append function performs at O(1) Inserting an element at the front and shifting all elements performs significantly worse than appending an element at the end of the list For the insert function, if the array is empty, there are no comparison operations that need to be performed and you can immediately add the new element Binary search can be used on an unsorted array to significantly improve its performance from O(n) to O(1) Because the update algorithm depends on using linear search, its performance is O(1) in the worst case scenario True If you search for and delete an element in an unsorted array and then shift the rest of the elements to fill the hole, the worst case performance is O(n) If you search for and delete an element in an unsorted array and then move the last element to fill the hole, the worst case performance is O(n)True or False For each statement below, indicate whether you think it is True or False If you have an array with no “holes”, the append function performs at O(1) Inserting an element at the front and shifting all elements performs significantly worse than appending an element at the end of the list For the insert function, if the array is empty, there are no comparison operations that need to be performed and you can immediately add the new element Binary search can be used on an unsorted array to significantly improve its performance from O(n) to O(1)Create a 1D integer array of size 17. Fill each index with a random value ranging from 1 to 359 inclusive. You will then design and implement the Random Sort algorithm using the following methods: Create a method called check_if_sorted (). It should take in a 1D integer array and return a boolean value. It should return TRUE if the array is sorted in nondescending order, and FALSE otherwise. Hint: If you compare elements in the array and a pair is in the wrong order, that would mean the array is not in non-descending order. Create a method called shuffleArray (). It should take in a 1D integer array and return a 1D integer array. Shuffle the array so that the values are in random different indexes, and return altered array. Hint: There are many approaches to solve this problem – making a second array in the shuffleArray () method might be part of the answer. Create a method called PrintArray (). It should take in a 1D integer array and return nothing. Simply print the current values…
- True or False For each statement below, indicate whether you think it is True or False. For the insert algorithm, if you use binary search to find the location to insert the new element, it will improve the overall performance of the algorithm to O(log n) For the update algorithm in a sorted array, all you have to do is use linear or binary search to find the element you want to change, and if you find it, you only need to change it to the new value Binary search can be used on an unsorted arrayBinary Search: Use the binary search method to find (or fail to find) the following numbers in the array provided. Sketch out the stages of each search: [1,5,8,14,25,26,33,42,52,53,54,56,64,74,93,104] 1. Look for 42. 2. Look for 67.Sorting is a basic issue with arrays in which the goal is to find the target element in the array. Choose from the following options: False
- Select true or false for the statements below. Explain your answers if you like to receive partial credit Select true or false for the statements below. Explain your answers if you like to receive partial credit Which of the following is true about searching elements in an unordered array? With the data is unsorted, search is O(n) because if the element you are looking for is not there, you have to check every element in the array If you start at the end of the array and traverse to index 0, search improves to O(log n) because you only have to look at half of the array If you get lucky with checking the first element and find it immediately, then the worst case performance of search improves to O(n^2) Which of the following is true about searching elements in an ordered array? You cannot use binary search on an ordered array so the performance is O(n) If there are no holes in the array and the elements are all next to each other, then the performance for search improves to…Hint: You can use any of these coaching to generate a random integer.
