- Refer to the following method that finds the smallest value in an array. /** Precondition: arr is initialized with int values. * Oparam arr the array to be processed Greturn the smallest value in arr public static int findMin(int[] arr) { int min = /* some value */; int index = 0; while (index < arr.length) { if (arr [index] < min) min = arr [index]; index++; } return min; } Which replacement(s) for /* some value */ will always result in correct execu- tion of the findMin method?

- You have made a device that automatically measures both distance from a magnet and the magnetic field strength at that distance. The device sends the pair of data to your computer as a pair of real numbers. However, the device moves back and forth as it takes data, so neither the field measurement nor the distance measurement arrives in ascending or descending order. Write a code vector_sort that receives a two-dimensional array of numbers and sorts them based on either the first column or the second column (this must be an input to the function. The function must also either sort high-to-low or low-to-high, based on an input value. Write a main function that can read up to twenty pairs of data. The main function must also input whether you want to sort high-to-low or low-to high. It must also input whether you want to sort on magnetic field or distance. Finally the code must print the pair data as originally entered and then, after calling vector_sort, the ordered pair data. C Programarrow_forwardHomework 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…arrow_forwardWrite a program to allow a user to play the game, Hangman. DO NOT USE AN ARRAY The program will generate a random number (between 1 and 4581) to pick a word from the file - this is the word you then have to guess. Note: if the random number you generate is 42, you need the 42nd word - so loop 41 times picking up the word from the file and not doing anything with it, it is the 42nd you need. Here is how you will do this: String word: for (int k=0; k<41; k++) {word=scnr.nextLine(); }//end loop and now pick up the word you want word=scnr.nextLine() //this is the one you want The user will be allowed to guess a letter as many times as it takes - but 10 wrong guesses and they lose!! Eventually either they won or lost. In case they lost print out the answer. Javaarrow_forward
- Heapsort has heapified an array to: 91 41 13 34 63 55 and is about to start the second for loop. What is the array after the first iteration of the second for loop?

- 8arrow_forwardNote: Set a random seed of 100 for this assignment. All arrays should contain random numbers between 0 and 1 (zero is inclusive). Create a one-dimensional array of twenty float random numbers. Assign the sum of these values to Q1. Assign the max of these values to Q2. Create a four by five array of random numbers. Take the minimum values in each array and create an array of those values. Assign it to Q3. Assign the mean of all the array values to Q4. Create an array with the following values: 2, 3, np.nan (this should represent a missing value), and 5. Use a numpy function to find the sum of the values in this array. Assign the sum to Q5 (you should expect a numerical value here). Create two separate arrays each containing four random numbers. Concatenate the two arrays and assign it to Q6. Create a four by four array of random numbers and call it q7. Concatenate this array with itself and assign it to Q7. Create a two by four array of…arrow_forward
