Why it is showing Doubt over there?
@cbcao263 when you search for mid point after assigning the midpoint->next to node* b you should make midpoint->next =NULL so that when you call mergesort(a) this will go upto only mid not again for the entire list.
How can I do that? Please tell.
when you assign m-next to b then after line 91 of your code write m->next=NULL.
What will be it’s benefit, Why we took m->next=NULL.
when you call mergersort(a) you are supposed to sort upto midpoint only in this function,
for this your function should stop at midpoint and to stop it midpoint->next should be put as NULL
