Problem with the third test suite

Asif Newaz on 13 Mar 2020

in 3rd case,
they intersect at two points.
In geometry, tangent circles (also known as kissing circles) are circles that intersect in a single point.

Test	Status	Code Input and Output
1	Pass	x1=[0,0]; x2=[5,5]; r1=3; r2=2; assert(isequal(touch(x1,x2,r1,r2),0)) y = logical 0
2	Pass	x1=[0,0]; x2=[3,4]; r1=3; r2=2; assert(isequal(touch(x1,x2,r1,r2),1)) y = logical 1
3	Fail	x1=[2,1]; x2=[3,4]; r1=4; r2=2; assert(isequal(touch(x1,x2,r1,r2),0)) y = logical 1 Assertion failed.
4	Pass	x1=[-1,0]; x2=[3,-3]; r1=3; r2=8; assert(isequal(touch(x1,x2,r1,r2),1)) y = logical 1
5	Pass	x1=[-5,-5]; x2=[5,5]; r1=5; r2=5; assert(isequal(touch(x1,x2,r1,r2),0)) y = logical 0
