Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

In the C(89) standard of C programming language Suppose you are given an array of integers. You want to insert a number x to the array and rearrange so that all the elements are less than or equal to x are before x, and the elements after x are greater than x. For example, suppose the list is {3, 2, 7, 0 1, 5} and x is 4, since 3, 2, 0, and 1, are less than or equal to 4, 7and 5 are greater than 4, the new array is {3, 2, 0, 1, 4, 7, 5}. The new array has the length of n+1 where n is the length of the input array. Example input/output #1: Enter the length of the array: 10 Enter the elements of the array: 3 5 14 03 92 8 11 Enter the number for insertion: 3 Output: 3 1 0 3 2 3 5 4 9 8 11 Example input/output #2: Enter the length of the array: 8 Enter the elements of the array: 5 0 1 3 4 1 7 3 5 Enter the number for insertion: 6 Output: 5 0 4 1 3 5 6 13 7 1) Name your program arrays.c 2) Include the rearrange( ) function to rearrange the array: void rearrange(int *a, int n, int…
[] [] partite_sets In the cell below, you are to write a function "partite_sets (graph)" that takes in a BIPARTITE graph as its input, and then returns a single list whose two entries are the partite sets of the graph as lists (the order of the sets outputed does not matter). After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (partite_sets({"A" : ["B", "C"], "B" : partite_sets({"A" : ["B", "C"], "B" : ["A"], "C" : ["A"]}), ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]})) This should return [["B","C"], ["A"]] [["A","D"], ["B","C"]] (the order in which the entries appear does not matter) Python Python
