题目链接:http://codeforces.com/problemset/problem/1183/D 思路: 这个题真是折磨死我了,我一开始用的方法是先用a数组存储数值出现的次数,然后再用b数组记录出现该次数的次数,下表即次数,值即次数的次数,然后从后往前遍历,如果次数的次数大于1,就加到前面, Read More

题目链接:http://codeforces.com/problemset/problem/1183/C 思路 这个题就是尽量玩a类型,就是求如果能玩这个游戏,玩a多少次,一开始我是从最大的值到0遍历,发现超时,然后我就用二分法求,二分果然快。 AC代码 Read More

题目链接:http://codeforces.com/problemset/problem/1183/A 思路 其实就是模拟,就是求输入的数值中每一位相加的和能否被4整除,就是将每一位的数值放入数组中,相加求和,不能被整除就加1,要注意进位。 AC代码 Read More

题目链接:http://codeforces.com/problemset/problem/1152/B 思路 这个一开始我觉得看起好像挺难的,但是我就想试一试嘛,然后我就模拟了一下这个过程,就是这输入的数据变成二进制,让该数从第一个1开始往后都变成1,然后异或就是将二进制数中的0变成1,1变成0。 Read More
