    WHERE CAN I MEET A NICE GUY

    Then we find letter 'e' which is righter that found 'h'. If we find the whole word 'hello' in such way, obliviously, answer is YES. Now let's prove that if answer exists, we find it. Let see on position of the 'h' in right answer. If we move it to the first 'h' in our string, nothing changes. But now we can say that our greedy chat room codeforces solution correctly Fast flirting let's do such with the second letter, and so on.

    We have greedy algorithm with work time O nwhere n - length of the input. Problem B. Coins This problem also have greedy solution: we run down all number from 2 and greater and while denomination of the last added to answer coin is divisible by current number, we divide and increase answer.

    You can prove correctness, if you take a look at prime factorizations of coins' denominations. In each next denomination each prime have less or equal power than the current one it's equivalent to ' a divide b '. So, in the optimal answer sum of degrees decreasing at exactly one.

    Our greedy algorithm do exactly what it need. Problem C. The first thing we notice - beautiful sequence is can be determined with any member. The next thing chat room codeforces solution at least one tree will remain the same height. Prove: let's fix height of the first tree, and correct heights of all other ones. Obliviously, they all remain positive.
