B"International Coding Procedures Company (ICPC) writes all its code in Jedi Script (JS) programming language. JS does not get compiled, but is delivered for execution in its source form. Sources contain comments, extra whitespace (including trailing and leading spaces), and other non-essential features that make them quite large but do not contribute to the semantics of the code, so the process of minification is performed on source files before their delivery to execution to compress sources while preserving their semantics. You are hired by ICPC to write JS minifier for ICPC. Fortunately, ICPC adheres to very strict programming practices and their JS sources are quite restricted in grammar. They work only on integer algorithms and do not use floating point numbers and strings. Every JS source contains a sequence of lines. Each line contains zero or more tokens that can be separated by spaces. On each line, a part of the line that starts with a hash character ('#' code 35), including the hash character itself, is treated as a comment and is ignored up to the end of the line. Each line is parsed into a sequence of tokens from left to right by repeatedly skipping spaces and finding the longest possible token starting at the current parsing position, thus transforming the source code into a sequence of tokens. All the possible tokens are listed below: Note, that during parsing the longest sequence of characters that satisfies either a number or a word definition, but that appears in the list of reserved tokens, is considered to be a reserved token instead. During the minification process words are renamed in a systematic fashion using the following algorithm: The goal of the minification process is to convert the given source to the shortest possible line (counting spaces) that still parses to the same sequence of tokens with the correspondingly renamed words using these JS parsing rules. The first line of the input contains a single integer n ( 0 "...
