My last exam tomorrow need help :(

Posted 13 September 2017 - 09:37 AM

tomorrow is my last exam the subject is Data Structures , the anxiety kicked in :( :helpsmilie:

its a very critical exam if i fail i will not be able to take the next subjects .

i have studied
- red/black , bst,avl, 2-3 trees
- in order post order preorder , reconstruct trees
- hashing extended , open addressing chaining etc..
- lists.. not so good i meaan they are easy to make them when writing a program
but im so confused with sorting etc

for example last time in the exam we had an excercise saying " if you have 2 lists, sort one ascending and the other descending and merge them" i was blacked out lol

i dont know what to read about lists etc or what else to read

Is This A Good Question/Topic? 0

I would advocate not getting 'blacked out' on a test.

It's a giant topic.. can you narrow down your problems with it?

Have you tried data structures visualized?

Maybe try doing? Take what you learned and try applying it and working it out.

got a question

in open addressing double hashing the algo is like this

1) apply h1 function if empty done
2) else h2 function => (h1 + h2) mod m if empty done
3) else h = (h1+h2) mod m if empty done else step 3

the m stands for size of array?
