# Using the Python language, have the function IntersectingLines(strArr) 
# take strArr which will be an array of 4 coordinates in the form: (x,y).
# Your program should take these points where the first 2 form a line and 
# the last 2 form a line, and determine whether the lines intersect, and if 
# they do, at what point.
# For example: if strArr is ["(3,0)","(1,4)","(0,-3)","(2,3)"], then the line 
# created by (3,0) and (1,4) and the line created by (0,-3) (2,3)
# intersect at (9/5,12/5). Your output should therefore be the 2 points in 
# fraction form in the following format: (9/5,12/5). If there is no denominator 
# for the resulting points, then the output should just be the integers like so: (12,3).
# If any of the resulting points is negative, add the negative sign to the 
# numerator like so: (-491/63,-491/67). If there is no intersection, your 
# output should return the string "no intersection".
# The input points and the resulting points can be positive or negative integers.


# Ex: Input = "(9,-2)","(-2,9)","(3,4)","(10,11)" Output = "(3,4)"

# Ex: Input = "(1,2)","(3,4)","(-5,-6)","(-7,-8)" Output = "no intersection"
