题目大意:给出一幅画,找出里面的象形文字. 要你翻译这幅画,把象形文字按字典序输出. 思路:象形文字有一些特点,分别有0个圈.1个圈.2个圈...5个圈.然后dfs或者bfs,就像油井问题一样,找出在同一块的0,找出在同一块的1,分别标上记号. 对于每个同一块的1,如果它们只和1个‘0’的块相邻,就表明这个象形文字没有圈.如果和2个‘1’的块相邻,就说明这个象形文字有一个圈.依此类推...和6个‘1’块相邻的就有五个圈. 最后统计一下每个象形文字和多少不同的块相邻,排一个序,输出. 要注意的是,…

思路:一开始对k没有理解好,题意说交换k次,如果我们不需要交换那么多,那么可以重复自己交换自己,那么k其实可以理解为最多交换k次.这道题dfs暴力就行,我们按照全排列最大最小去找每一位应该和后面哪一位交换.k = 0没判断好WA了2发... 如果k >= len - 1,那么最大最小就是直接sort非前导零的答案.如果k < len - 1,那么我们交换肯定从最大位数交换,比如现在求最大值,那么我们从第一位依次判断,如果该位不是他后面最大的,那么就和后面最大的交换(如果最大的有多个,那么就每个…
