Codility: Was given online assessment containing 2 programming questions and 1 sql question.
- Minimum number of characters to delete from a string so that each character appears unique number of times. Note: You can delete all occurances of characters.
eg: “aaaabbbb” -> 1 “a” or 1"b" would make “a” and “b” appear unique number of times.
- Given number in binary form, if its even -> you can divide it by 2; if its odd -> you can substract 1 from it. You can repeat above steps as many times as you want to reach 0. How many steps it took to reach zero?
- SQL question to select records from two tables using joins etc.
