11536 - Smallest Sub-Array（滑动窗口）

该题其实就是lrj讲的滑动窗口的一个小小变形，只不过这个窗口的大小是可变的。 具体方法其实和例题Shuffle类似，用首尾两个指针维护窗口，用一个数组cnt记录1~k中每个数字在窗口中出现的次数，用一个变量c记录窗口中只出现了一次的数字的个数。 这样只要c==k这就是一个满足条件的答案，取最小答案即可。由于每个元素都只插入删除一次，所以时间复杂度为O(n)。该算法还有一个名字叫“取尺法”，特点是处

题目大意：输入一串数字，将其分为两组，每组随机搭配，组成一个整数，整数的不能以0开头，除非只有个位，求两个整数差的最小值分析：DFS暴搜掉。很容易想到一个整数的位数为n/2，另一个为n-n/2时，差最小，所以，用next_permutation枚举。特殊情况需要注意，只有两个数字且其中一个为0，没注意这个，贡献了两个WA，晕死代码：#include #include #include #inclu
