Swift Challenge:a problemset you can read the statement of each problem in 60s.

Hi guys,here I'd like to share my problem set in an interesting way. All the problems are created by myself.

They contain my aesthetic of problems: the neater,the better. It should be also interesting and best to have educational significance.

You can find the editorial for all the problems in the link,so I will only write down some interesting points under the statement.

Let's go :)

1.Increasing and Decreasing

Construct an array $$$a$$$ consisting of $$$n$$$ integers which satisfies the following conditions:

  • $$$a_1=x,a_n=y$$$;
  • $$$a$$$ is strictly increasing;
  • if we denote $$$b_i=a_{i+1}-a_{i}$$$ for $$$1 \leq i \leq n-1$$$, then $$$b$$$ is strictly decreasing.
