CS Problems

These are a collection of some interesting problems that I came up while reading CS. I'll be adding more.

  1. Given any 2 Rubik's Cube configurations, find out the minimum distance between them (open problem).
  2. Given any matrix, a legal move defined as performing a cyclic shift on a column or a row. Given two matrices with exactly the same elements, find the minimum legal moves required to obtain second matrix from the first one.
  3. There are MM shoppers and CC counters at hyper mall. kthk^\text{th} shopper takes tkt_k time to shop and bkb_k time to complete the billing process. Given the values tit_i and bib_i, find an way to arrange the shoppers at the counters such that the last shopper leaves as early as possible.
  4. You are given the rates of stocks for the next 30 days and while you can buy and sell multiple times, you can only hold at most one position at any time. Determine the maximum profit which you can make.
  5. For any set K={a1,a2,,an}K = \{a_1, a_2, \dots, a_n\} of integers, SXOR(K)=a1 XOR a2 XOR  XOR an\text{SXOR}(K) = a_1 \text{ XOR } a_2 \text{ XOR } \dots \text{ XOR } a_n. Given any set SS, find the set AA such that ASA \subseteq S and SXOR(A)\text{SXOR}(A) is maximal.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.
