Consider your roll number as an array. • Write Bubble Sort Function to sort your roll number in Descending Order. 1 Also • If the array is sorted in 1st, 2nd, OR 3rd Pass, Loop should break after that pass. • In the second pass, Number of Comparisons should decrease by One and so on You are required to dry run your above code. Hint: for 1st value of i there will be 4 steps of j (Pass1) · for the second value of i there will be 3 steps of j (Pass2)

Matrix Multiplication• Write a multiplication function that accepts two 2D numpy arrays,and returns the product of the two. This function should test that thearrays are compatible (recall that the number of columns in the firstmatrix must equal the number of rows in the second matrix). Thisfunction should test the array sizes before attempting themultiplication. If the arrays are not compatible, the function shouldreturn -1.   solve in python

In this assignment, you will decide how to keep the inventory in the text file. Then your program must read the inventory from the file into the array. Each product must have a record in the file with the name, regular price, and type. There are several options for storing records in the file. For example, • each value takes one line in the file (i.e., three lines for one product). Then you must take care of correct handling of the ends of the lines; • all values are in one line that can be read as a string. Then you must handle the parsing of the string; • all values are in one line separated by a delimiter. Then you must handle a line with delimiters. Assume that the inventory does not have more than 100 products. But the actual number is known only after the reading of the file. Once you can read data from the file into the array, you must add a new property to the product class – a static variable that holds the number of products in the inventory. Its value must grow as reading…

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…
