The "output" of your solution is the state in which it left the input qubit. Your code should have the following signature: namespace Solution { open Microsoft.Quantum.Primitive; open Microsoft.Quantum.Canon; operation Solve (q : Qubit, sign : Int) : () { body { // your code here }...
Why my solution is giving TLE even my time complexity is inside the range according to this post Can someone please help me this is my solution https://codeforces.com/contest/1615/submission/163142677 → Reply Penguin07 3 years ago, # ^ | 0 Time complexity of your solution is O(T...
In brief, on the contests held by Codeforces rules you write solutions to the problems that are tested during the contest on a very small number of tests. Those who have passed that set of solution tests, their authors can block (refuse to resend the solutions of this task in future even...
Once Arpa came up with an obvious problem: Given an array and a number x, count the number of pairs of indices i, j (1 ≤ i < j ≤ n) such that , where is bitwise xor operation (see notes for explanation). Immediately, Mehrdad discovered a terrible solution that no...
题目链接 :http://codeforces.com/contest/742/problem/B 题意:给你n个数和一个x,问你n个数中有几对(ai , aj)的xor值为x,而且j>i。 题目比较简单看一下代码就会秒懂了。还有要注意结果用longlong来存。 1 2 3 4 5 6 7 8 9 10 11
【题目链接】:http://codeforces.com/contest/742/problem/B 【题解】 用个map记录1..i-1里面x xor a[i]的值有多少个; 则那些数字都能和a[i]进行xor运算取得a[i]; 因为a xor b = c 则c xor b = a 且c xor a = b; O(n)枚举搞一下就好; ...

CodeForces 742B Arpa’s obvious problem and Mehrdad’s terrible solution (暴力枚举),题意:求定n个数,求有多少对数满足,ai^bi=x。析:暴力枚举就行,n的复杂度。代码如下:
