In the line 24 of the code above i have used the condition
while( fast!=NULL and fast->next!=NULL) , i am all getting all test cases correct but if i change this condition to
while( fast->next !=NULL and fast !=NULL) , i dont get all test cases correct.
Why this is happening as both the ways mean the same ?
both are different conditions actually
if fast is null then fast->next will give you runtime error
but if you use this condition fast!=NULL and fast->next!=NULL
then first fast is checked if first condition false then compiler didn’t check second because what will be second answer will be false
because false && true = false
false&& false = false;
i hope you got the point
