interchnage the position of these two conditions

Sir, Why it is creating issues.
First time it happened with me and literally shocked with this condition.

#4

and condition get checked from left to right.

so first we need to check for fast!=NULL condition and then after fast->next!=NULL

let say our fast is NULL and if we try to check conditions in this order
fast->next!=NULL && fast!=NULL
then first fast->next!=NULL will be checked but because fast is NULL we cannot do NULL->next!=NULL ,hence it will give error.

Okayy Sir, Thanks a lot for this one.
