Under the guidance of the Chinese Institute of Electronics, the Modern Educational Technology Branch of the Chinese Institute of Electronics decided to hold the "2023 First Undergraduate Algorithm Competition" for full-time graduate students and college students in universities across the country. Through such competitions, students' popularity can be improved, and students can also get more authoritative awards. Therefore, the first college students' algorithm contest contains a lot of gold.

Any calculation step performed in the algorithm can be decomposed into basic executable operation steps, that is, each calculation step can be completed in a limited time. The algorithm represents a systematic method to describe the strategy and mechanism for solving problems.
