1. ArrayList
2. encode/decode string
As an example, for the input string "bJbb++b":
/* 1. 'b' occurs 4 times.
* '+' occurs 2 times.
* 'J' occurs 1 times.
* 2. Thus, the following encodings are assigned:
* 'b' -> "1"
* '+' -> "01"
* 'J' -> "001"
* 3. By concatenating the encodings together, we get:
* "10011101011".
*/

1. word ladder
2. soduku solver
3. soduku valid
4. AB index from string
5. diff
6. word splitter
7. 2 sum, 3 sum
8. Tree related
9. LRU cache
10. Bytes Prefix
Good luck.
