interchange position of these two conditions.

thanks working now but what was the error

#5

condition get checked from left to right.
so obviously we should first check fast!=NULL and then only fast->next!=NULL.

if we first check fast->next then it might happen that fast is NULL so in that case NULL->next will give error .

that is why we first check whether fast is null of not and then only jump to next conditon

#6

if it returns array then it will check for fast and condition should become false is it not the case?

#7

so it is giving segemtaion fault at null->next is that the case?

#8

that was typo . . . . . . . . :rofl::rofl:
