Introduction To Algorithm

The word Algorithm means “a process or set of rules to be followed in calculations or other problem-solving operations”. Therefore Algorithm refers to a set of rules/instructions that step-by-step define how a work is to be executed upon in order to get the expected results. 

Advantages of Algorithms:

  • It is easy to understand.
  • Algorithm is a step-wise representation of a solution to a given problem.
  • In Algorithm the problem is broken down into smaller pieces or steps hence, it is easier for the programmer to convert it into an actual program.

Apple and Orange – Hacker Rank Solution

Problem:

Sam’s house has an apple tree and an orange tree that yield an abundance of fruit. Using the information given below, determine the number of apples and oranges that land on Sam’s house.

In the diagram below:

  • The red region denotes the house, where  is the start point, and  is the endpoint. The apple tree is to the left of the house, and the orange tree is to its right.
  • Assume the trees are located on a single point, where the apple tree is at point , and the orange tree is at point .
  • When a fruit falls from its tree, it lands  units of distance from its tree of origin along the -axis. *A negative value of  means the fruit fell  units to the tree’s left, and a positive value of  means it falls  units to the tree’s right. *

Function Description

Complete the countApplesAndOranges function in the editor below. It should print the number of apples and oranges that land on Sam’s house, each on a separate line.

countApplesAndOranges has the following parameter(s):

  • s: integer, starting point of Sam’s house location.
  • t: integer, ending location of Sam’s house location.
  • a: integer, location of the Apple tree.
  • b: integer, location of the Orange tree.
  • apples: integer array, distances at which each apple falls from the tree.
  • oranges: integer array, distances at which each orange falls from the tree.

Input Format

The first line contains two space-separated integers denoting the respective values of  and .
The second line contains two space-separated integers denoting the respective values of  and .
The third line contains two space-separated integers denoting the respective values of  and .
The fourth line contains  space-separated integers denoting the respective distances that each apple falls from point .
The fifth line contains  space-separated integers denoting the respective distances that each orange falls from point .
