pensebien / intersecting_rec..rb
Last active October 1, 2016 09:10
This contains a function that finds the intersecting vertices of two rectangles given the rectangles vertices as two arrays. The arrays are given such that the two first elements are the coordinate of the base point of the rectangle, while the third element is the breath and the last element is the height of the rectangle. Example a=[1,1,2,3] x=…
#The function find the intersection point of two lines
def intersect_rec(a, b)
#Function takes the coordinate of horizontal and vertical line #Return the coordinate of the intersection
intersect = []
if a.length !=4 and b.length !=4
return "You did not enter a rectangle vertices"
end
x1 = a[0]
x2 = a[0]+a[2]
y1 = a[1]

Find the product of the elements in an Array without the element itself. [1,2,3], newArray = [6,3,2]
def product_of_elements_array(a)
i = 0
prod = 1
while i <= (a.length-1)
prod = prod * a[i]

This is a ruby code that check if the number you typed is a prime using the fastest method ever. Hint! Use square root algorithm
puts "Enter a number to to check"
number = gets.chomp.to_i
def abs(firstNum,secNum)
if firstNum > secNum
firstNum - secNum
else
secNum - firstNum

puts "Enter a number to find the square"
number = gets.chomp.to_i
puts "Enter the accepted error"
error = gets.chomp.to_i
def abs(firstNum,secNum)
if firstNum>secNum
firstNum-secNum
