Pattern matching on slices

大城市里の小女人 提交于 2020-02-03 13:24:48
问题 I did something like this, which works: let s = " \"".as_bytes(); let (space, quote) = (s[0], s[1]); I wanted to do something like this &[space, quote] = " \"".as_bytes(); But it gives me the error slice pattern syntax is experimental (see issue #23121) Is it possible to do something similar? 回答1: As the error tells you, slice pattern syntax is experimental. This means either the semantics are not clear or the syntax might change in the future. As a result, you need a nightly version of the

Implementing an algorithm that matches lids to jars of the correct size

爱⌒轻易说出口 提交于 2020-01-25 06:46:14
问题 The problem: We're given a list of jars and a list of lids (same size). For each jar, there is at least one matching lid and vice versa. In the lists that are given, both the lids and jars are scrambled randomly. I want to find an efficient algorithm to return pairs of matching lids and jars. My strategy: sort both sets, using an efficient algorithm (log(n), n = number of jars = numbers of lids). Then we can just match them two-by-two into a pair, which we add to a list that will be the

问题 I am going to attend the Instance Matching of OAEI, now I need to make my results to Alignment Format. In order to achieve it, I have learned official tutorials.(link:http://alignapi.gforge.inria.fr/tutorial/tutorial1/index.html). But there are many differences between the method taught and the method I want. In other words, I can't understand the API.

hashtag boundaries matching regex in javascript

问题 I'm trying to match a set of hashtags or words in a javascript string. (#hashtag|word) almost does it, except I'd like to consider word boundaries. \b(#hashtag|word)\b doesn't match the beginning word boundary, since of course '#' is not a word character. ideally i'd like to have something like a '\b' anchor that matches hashtags. Any idea? 回答1: What about insert word boundary inside the parenths : /(#\bhashtag|\bword)\b/ 回答2: If you want to use Twitter's official regular expression for

Using 'fastmatch' package in R

血红的双手。 提交于 2020-01-15 12:23:50
问题 I have to find indices for 1MM numeric values within a vector of roughly 10MM values. I found the package fastmatch , but when I use the function fmatch() , I am only returning the index of the first match. Can someone help me use this function to find all values, not just the first? I realize this is a basic question but online documentation is pretty sparse and fmatch has cut down the computing time considerably. Thanks so much! Here is some sample data - for the purposes of this exercise,
