Gold Medal Legend | It took him just four years to win the first gold medal in the NOI2024

(zero) A few years ago, there was an IOI silver medalist, when the media reported that he only started to learn Xinao in his first year of high school, and then passed the preliminary round of the NOIP improvement group in October, participated in the semi-finals of the NOIP improvement group in November and won the first prize with a score of 450+ (the full score of the previous NOIP improvement group was 600 points), won the NOI national gold medal in the summer of the second and third years of high school, and won the IOI international silver medal in the summer of the third year of high school. The media believes that he only started learning Xinao in his first year of high school because he did not have a NOIP award record in elementary school and junior high school. But some people say that he didn't start learning in the first year of high school, but in elementary or junior high school.

(1) On July 23, the Chinese Computing Society released the "Announcement of the Winners of the CCF NOI2024".

The champion of NOI2024 is Zhang Dingjiang, a student from Chongqing No. 8 Middle School. Chongqing No. 8 Middle School is one of the Dragon Ball schools in Chongqing. Zhang gave me the impression that it took a short time to study Xinao. In other words, he has a steep ascension curve.

Zhang won the second prize in the CSP2020 entry group in the first year of junior high school, which shows that Xinao has just started. In this way, it seems that Zhang will not start learning C++ and algorithms very early.

According to People's Daily Online's "No. 1 in the Country! Chongqing No. 8 Middle School created the best results of the Chongqing team in this competition", Zhang began to learn programming at the age of 12. At the age of 12, it is usually the first half of the sixth grade and the second half of the first year of junior high school. When Zhang entered the first year of junior high school, he was still a novice to information competitions. Xiaobai means "I don't understand at all" or "I only understand a little", so it can be seen that Zhang started learning Xinao around the time he entered the first year of junior high school in September (according to local parents, he started learning in the summer vacation of the year of Xiaoshengchu, so it can also be regarded as the first year of junior high school).

A year later, in the fall of 2021, Zhang won the double first prize in CSP-JS2021, with 300 points in the introductory group and 190 points in the improvement group. The questions of CSP-JS2021 are very difficult, the difficulty of the four questions in Group J is popular-, popular, popular, and improving, and the difficulty of the four questions in Group S is improving, improving, improving+, and provincial selection. From here, it can be seen that Zhang has made great progress between the fall of 2020 and the fall of 2021.

In October last year, Zhang scored 320 points in CSP-S2023, ranking 381st out of 11,765 people who participated in the semi-finals of Group S, which is a good result. A month later, Zhang scored a perfect score of 400 points in the NOIP2023, tied for the first place in the country. NOIP2023 dozens of people across the country received perfect marks. In March this year, Zhang was selected for the Chongqing team with the second place.

After another four months, that is, this month, Zhang achieved the first place in the NOI2024. Observing the growth trajectory of Zhang's "score", it can be found that Zhang has been making steady and rapid progress. Zhang may be the most improved player in the CSP-JS era.
