Arunabha is great in maths. But he is not a good coder. He wants to write a program to check, in a graph with coordinates X and Y, if three points fall on the same line or not.
INPUT:
Six integers x1, y1, x2, y2, x3, y3 separated by whitespace.
OUTPUT:
Print “Yes” (without quotes) if all the points fall on straight line, “No” (without quotes).
otherwise.
CONSTRAINTS:
-1000 <= x1, y1, x2, y2, x3, y3 <= 1000
