AUTHOR:

DIFFICULTY:

Simple

PREREQUISITES:

Basics of Physics and coordinate system.

PROBLEM

Our aim is to find the time taken by Chef and Kefa and then compare those time.

EXPLANATION

Given for each test case:
X1 -Coordinate of Chef’s Restaurant
X2 -Coordinate of Kefa’s Restaurant
X3 -Coordinate of Secret Recipe

V1 -Chef’s running speed
V2 -Kefa’s running speed

Time=\frac{Distance}{Speed}

So in order to find time we need speed, which we already have and distance.
To calculate distance we use following formula:

Distance=|Difference of coordinates|

And finally the code snippet:

d1=abs(x1-x3);
d2=abs(x2-x3);
//remember t1 and t2 must be decimal numbers with up to 7 decimal places. 
//Also don't forget to type cast. 
t1=d1/v1;
t2=d2/v2;
//Now check the winner of race
if(t1>t2)
print("Kefa");
else if(t2>t1)
print("Chef");
//Don't forget draw case.
else
print("Draw")
