Tags: prefix expression evaluate Link: http://pat.zju.edu.cn/contests/ds/3-07 Arithmetic expressions include prefix, infix, and suffix. Prefix expression indicates that a binary operator is located before two arithmetic operations. For example, the prefix expression of 2 + 3 * (7-4) + 8/4 is ++ 2*3-7 4/8 4. Please de

The structure of the standard trie is1 class Trienode {2 trienode[] child; 3 Char Curchar; 4 Hashset HashSet; 5 int freq; 6 }But we don't need Freq or hashset in this question, but to show that the current node is not the end of a word, we set a Boolean isleaf.The reason for doing this is to consider the following two scenarios:1. If you insert AB, but search for a, you should return false, search prefix should return true2. In

　　Test instructions: Gives a string, each asking for x and y to calculate theproduct (mod9973) of the value (ASCII code value-28) of each character from X to Y. Analysis: The first idea must be to figure out the prefix product for each location, and then just f[y]/f[x-1]. However, each prefix product has been mod9973, it can not directly come to the result, so the use of inverse element. Since A/b (mod p) p
