Problem Statement: You are given n points in a plane. Whenever we find three points that are collinear, we draw a line through them. How many different lines are there? Come up with an efficient algorithm. First, explain your solution. Then provide a code written in C++ or JAVA or python. Or you can just give me a clearly written pseudocode.Hints:0. We take three points and see if they are collinear or not. If they are collinear, we determine the line's equation. And we store the slope and x intercept of that line in a map data structure. We store the pair (m,c) in a map of pairs. We store (m,c) because this pair defines the line.1. Every time we find such a line, we save it's slope and x intercept.Suppose Pi,Pj and Pk are collinear. And the equation of the line is: y=mx+cWhere m=yj−yixj−xiand c=yi(xj−xi)−xi(yj−yi)xj−xiWe can store m and c as floating point values but that is prone to small errors. So, we can store m and c as irreducible fractions. Suppose m=m1m2 and c=c1c2 where…

Help Me With C Programming On their way down the river, Jojo and Lili saw two frogs in X1 and X2 respectively. The two frogs are seen jumping up and down happily in the same direction, which is coming to Jojo. After noticing the two frogs, Jojo and Lili noticed that the speed of the two frogs was different. The first frog to start jumping from the X1 position has a speed of V1, while the second frog that starts jumping from the X2 position has a V2 speed. Jojo guessed that the "YES" of the two frogs would be in the same position in a given T time, while Bibi guessed the "NO" of the two frogs would never be in the same position in that time. Help Jojo and Lili take into account the frog's movements to determine if their guess is correct. Format Input The first line of input consists of a series of integers namely X1, V1, X2, V2, T. X1 and V1 are the starting positions and jumping speeds per second of the first frog. X2 and V2 are the starting positions and jumping speeds per second…

Question: Chocolate Thief Problem I gave some chocolates to students for their extraordinary performances. A chocolate is a cube shaped thing, which has length, width and height. All the students got the same amount of chocolates; their dimensions may be different but the volumes are the same. Now some of the students are claiming that there is one chocolate thief among them. So, it's not an easy task for me to find the chocolate thief, so I am asking your help. You are given the names of the students and the dimensions of their chocolates; you have to find the name of the chocolate thief. You can assume that there can be at most one thief and if there is a thief, he took some portion of the chocolate from exactly another student (not students).

1. Write a program in C that will read a number as input. Check whether the number is prime number or not. Hint: A prime number cannot be divided by any other numbers without leaving a remainder. An example of a prime number is 13. It can only be divided by 1 and 13. Dividing a prime number by another number results in numbers left over e.g. 13 + 6 = 2 remainder 1 2. You are tasked to develop a C program that will generate a simple calculator using switch case statement. Hint: Program takes an arithmetic operator +, -, *, / and two operands from the user. Then, it performs the calculation on the two operands depending upon the operator entered by the user
