读入建立一棵字母树,并且每到一个节点就增加这个节点的覆盖数. 然后再重新扫一遍,一旦碰到某个覆盖数为1就是这个单词的最短前缀了. 不知为何下面的程序一直有bug……不知是读入的问题? type node=record w:longint; go:array['a'..'z'] of longint; end; var i,n,tot:longint; s:string; a,ans:..] of string; t:..] of node; procedure getintree(s:strin…

直接用Trie树即可. 每个节点统计经过该点的单词数,遍历时当经过的单词数为1时即为合法的前缀. type arr=record next:array['a'..'z'] of longint; w:longint; end; ; ..maxn] of arr; s:..maxn] of ansistring; i,j,m,n,now,num:longint; begin while not eof do begin inc(n); readln(s[n]); end; num:=; to n…

Shortest Prefixes 题意:输入不超过1000个字符串,每个字符串为小写字母,长度不超过20:之后输出每个字符串可以简写的最短前缀串: Sample Input carbohydrate cart carburetor caramel caribou carbonic cartilage carbon carriage carton car carbonate Sample Output carbohydrate carboh (carbo不止一个字符串含有,所以不能作为简写符号)…
