The beginning of the matter happened about eight years ago. It seemed that I had just finished the high school entrance examination and was admitted to the key high school in our city. My parents were also very happy. During the summer vacation, I wanted to have fun and welcome a fresh high school career, but after a few days, I came from my neighbor's house and shocked our entire family home: Brother Cheng of the opposite family (one year older than me, and was only 17 years old at the time, and one year earlier than me) participated in the National Youth Informatics Olympic League, but actually won the first prize in our city. According to our admissions committee regulations, we will give a minimum 20 points extra points in the college entrance examination. Moreover, Brother Cheng was just in the first year of high school and can participate in the competition every year in the future. According to his current level, it is estimated that there is no problem to be admitted to a 211 university in the future.
