Hi @Divya_321

In lines 50 and 56 instead of compare sign(==) you need to use assignment operator (=).

Hope it Helps.

@Nayan04 I have corrected line no. 50 and 56 but now every test case has failed what’s wrong in my logic, please specify error and correct it

Can you please explain your approach?

#5

the basic intuition that came to me is I am given
5 3
0 1
2 3
0 4
here I can say 0,1 ,4 are connected and they lie in one group I have marked same group by keeping parent of each node same here which is 0 (for ur clarity say A), and 2,3 are connected so it can be placed in another group so in order to show that 2 and 3 are in same group I have marked i’s parent t with group 2 (for ur clarity say B)so making say now in how many ways road can be constructid between these two gropus i.e. basic combination
no. of elements in group A X no. elements in group B i.e. 3X 2 = 6, this is my approach
now please correct my code
