AT2686 [ARC080A] 4-adjacent 题解

这道题目如果是暴力肯定不行，标签是入门，看着是个数学题。如何判断两个数的积是 \(4\) 的倍数呢？两个数中其中一个数含有因数 \(4\) 两个数的积中含有因数 \(4\)，即两个数都是 \(2\) 的倍数（但这两个数都不含因数 \(4\)）所以我们只要边读入边把 \(4\) 的倍数和是 \(2\) 的倍数但不

adjacent_difference()的使用

adjacent_difference()是位于numeric头文件中，用来比较序列中相邻元素的差值，并将它们的差值保存到另外一个序列上。因为第一个的前一个值为空，所以第一个元素会原封不动的复制到序列中，然后第二个元素和第一个元素相减结果作为新的第二个序列元素，再用第三个元素减去第二个元素
