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.

Question

use the partition function given when writing quicksort algorithm

3. The following is a new Partition algorithm using A[lb] as the pivot element. Assume that
ub> lb.
Partition (A[], lb, ub):
pivot
A[lb]
downlb - 1
upub + 1
while TRUE {
do {
up up 1
} while A [up] > pivot
do {
down + 1
} while A[down] < pivot
if down < up {
A[up]
down
}
A [down]
} else {
return up
}
Design a quicksort algorithm using the above Partition algorithm. Make sure that your
algorithm does not loop forever.

Python help. Using ( Heapq ) sorting algothrim create only one function def sortstring(filename): that takes in a file which has a bunch of sentences, each line of sentence consting of different length. Sort the setences from the lower length senteces to the highest length sentence. Print it after ( DON'T USE ANY SORTING BULT-IN FUNCTION ). Note: Keep note of time complexity as it should be able to run few 10,000 lines of sentences in few seconds.
With c programming and without pointer and function You are given an array of N positive integers. Find the maximum even values from the array. For finding the maximum even values from the array you can perform only one of the following operations. Choose any even value from the array. Choose any two(must be different) values from the array and perform summation on those two values. If it will even you can pick those two values. It is guaranteed that all the integers are distinct and at least one operation will exist in the given input. Input Format The first line contains a single positive integer N. The second line will contain N positive integers A1,A2,A3,A4…..An Constraints 1 <= N <= 10 1 <= A[i] <= 20 where (0 <= i < n) Output Format Print a single positive integer, the maximum even value. Sample Input 0 52 4 6 8 10 Sample Output 0 18 Explanation 0 In this case, we can choose 8 and 10, the summation is…
Computer Science Using Java, write a simple Insertion Sort program that can read in integers from a text file (line by line) and sort them into another text file. Use inFile and outFile for the input and output files, respectively. Also make sure that the algorithm keeps track of the comparisons and exchanges performed by the sort so that they may be printed out in the console after the sort is completed
