- Python Knapsack: you are carrying a knapsack with capacity to hold a total of weight C. You are selecting among n items with values A={a1, a2, ... , an} and associated weights W={w1, w2, ... , wn}. Here the weights and values are all positive. You wish to maximize the total value of the items you select not exceeding the given weight capacity, example, maximize sum_{a in A} such that sum_{w in W} <= C. Note that you can only select your items once. In Python, create function DP_K (C, A, W) as stated above. Input an array to the function to hold the backtrace. What is the best set of items for C = 30, A = [40, 110, 100] and w = [20, 30, 40]? This can be shown using auxiliary printing function.Answer in JavaScript Tim while preparing for his CAT exam, was studying the topic Number Systems. He encountered a loving da question: Given a number N, find the number of pairs (cy) where both x and y are less than N and Highent Common Factor(HCF) of x and y is 1. You have to solve the question for him. Note: 0 can be included within the pairs Input Specification: Input: The number N from which the pairs (x,y) should be obtained Output Specification: Return the total number of pairs Example 1: input1: 4 Output: 9 Explanation: The pairs can be (1,0) ,(0,1) (1,1) (1,2) (2,1) (0, 3) (3,1) (2,3) (0,2) So, a total of 9 pairsنقطة واحدة Let A = {a; b; c; d} and R= {(a; a); (b; c); (c; b); (d; d)} then R is Transitive Equivalent not transitive
- C-Language The goal of this problem is to find the smallest integer in a list of numbers. To help you with this task, please write a function called min() that finds and returns the smallest amongst two integers (be sure to also write a prototype for this function). The function thus takes two integers as input and returns the smallest of the two. This function will use an if statement with a condition that contains either "less than" or "greater than". Next, please use min() in your main function to work your way through an entire list of numbers in order to find its minimum. The first number you read gives the number of elements in the list of integers under consideration. You will then read the integer values, using min() to keep only the smallest integer read at each step. In the end, please print out the smallest integer in the list. Example Input 104 3 6 2 6 8 9 8 5 4 Output 2JAVA LANGUAGE CODE Postfix Calculator by CodeChum Admin One good implementation of computing infix expressions is to transform them to postfix and then evaluate via the postfix expression. Infix expressions is the common way of writing arithmetic expressions. The binary operator come between them as shown below: 2 * 5 + 9 - 10 / 20 In postfix expressions, the operands come first before the operator: 2 5 * 9 + 10 20 / - A stack can be used to evaluate postfix expressions. The operands are pushed onto the Stack and when an operator is found two operands are popped and the operation is performed and finally the result is pushed back onto the Stack. The final answer will be the lone element of the Stack. Input The first line contains a positive integer n representing the number of postfix expressions. What follows are n postfix expressions themselves. 5 10 20 + 30 15 2 * + 100 20 30 + / 90 20 10 + + 0 / 9 3 - 10 + 2 * Output A single line containing the result of…Weighted Job Scheduling in C language only please Problem statement: You are given a list of jobs where each job has a start time, finish time, and the profit associated with that job, find the maximum profit subset of non-overlapping jobs. Problem description: The problem wants you to find the maximum profit that you can make after performing a certain number of jobs such that each job has a certain condition that you can start a job only if the start time of the current job is greater than the finish time of the previous job. You are required to develop some algorithm such that the job start time and the finish time does not coincide with other jobs. Output: (Attached photo)
- C Programming Language (Code With C Programming Language) Problem Title : Visible Trees There is a legend about a magical park with N × N trees. The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees. On the second column, Bunga can see…Code in C++ Language STRING FLIP ALPHABET One of the simplest cryptography technique is to invert the characters such that the first character of the alphabet will be replaced to the last character, the second character be replaced to the second to the last, and so on. So all A's are turned into Z's, B to Y, C to X, and so on until X to C, Y to B, and Z to A. In a similar fashion, numeric characters will also be inverted such that 0 will become 9, 1 to 8, 2 to 7 and so on until 7 to 2, 8 to 1, and 9 to 0. Given a string composed of uppercase and lowercase letters, numbers, and spaces, your task is to invert them. You also must keep the case of the letters as is.

One approach is to use System.nano Time() where the current time is stored as a long integer equals to the number of nanoseconds. By subtracting the starting time in nanoseconds from the ending time in nanoseconds, you get the run time-in nanoseconds of a section of code. public static void main(String[] args) { int n1 = 10, n2 = 100, n3 = 1000, n4 = 10000; long n1Time, n2Time, n3Time, n4Time; n1Time AlgorithmA (nl); For example, suppose that AlgorithmA is the name of a method you wish to time. The following statements will compute the number of nanoseconds that AlgorithmA requires to execute: } public static long AlgorithmA (int n) { long startTime, endTime, elapsedTime; startTime = System.nanoTime (); int sum = 0; for (int i = 1; i 0 1 2.
