《中学科技》1990年第1期刊载了一道有奖征解题:问题一,将自然数按图1中的规则排列,每个自然数的位置都有坐标,如“3”所在位置的坐标为(1,1),问1990所在的位置的坐标是什么? 这个问题在数学竞赛中也已出现过,北京市1979年高中一年级数学竞赛第二试的第一题:问题二,在直角坐标平面的第一象限中,把坐标都是整数的点按以下方法编号: In the first issue of Journal of Science in Middle School in 1990, there was a prize exhortation: Problem 1, the natural numbers are arranged according to the rules in Figure 1, and the position of each natural number has coordinates, such as the coordinates of the location of “3” ( 1,1), What is the coordinate of the location of 1990? This question has also appeared in the math competition. The first question of the second test of the 1979 high school math competition in the first year: Question 2, in the Cartesian coordinate plane In the first quadrant, the points whose coordinates are all integers are numbered in the following way:
