some good points to think :-
1) Why are you alive
2) Is the array overflowing
3) will you ever be able to solve a graph question.yay!
4) The answer will be trivial always if its not its not worth solving
5) for xor a^b = a+b-2a&b xor of multi element set counts only odd no. of set bits
6) char values are '0' =48 'a' = 97 'A' = 65
7) two pointers are good way for array sum /length based questions
8) dp on sums?
9) make black boxes
10) min/max at central tandencies and just iterate +- 5 around it
11) Always use different array for coloring.
12) Null adjacency list will return from traversal.
13) Add once only in case of trees.
