awoo→Educational Codeforces Round 170 Editorial Bysavinov,12 years ago, translation, Hi, everybody! Recently, I tried to solve a problem. In this problem I had to determine, is number N sum of two squares? i.e.N = a2 + b2?, whereaandbare integer.N < 1015. Firstly,...
how come the sum of 2 natural numbers is a fraction??? my answer is because we aren't dealing with a natural finite number but I'm not sure how to mathematically explain it Any ideas?? (Before you rush into saying that the sum is wrong please do some research).....

Codeforces 85D Sum of Medians(线段树) 题目链接:Codeforces 85D - Sum of Medians 题目大意:N个操作,add x:向集合中加入x;del x:删除集合中的x;sum:将集合排序后,将集合中全部下标i % 5 = 3的元素累加求和。 解题思路:线段树单点更新,每一个点维护5个值。分别表示从该段区间中i % 5 = t的和。
E. Two Arrays and Sum of Functions(贪心) https://codeforces.com/problemset/problem/1165/E 题目大意: n代表n个数,然后输入a数组,a数组有n个,b数组有n个。然后你可以对b数组里面的数任意排序,最终目的是使得题目中的表达式的值尽可能的小。 具体思路:...
