StringHandler+splitByNewline(text: String) : Array+removeWhitespace(text: String) : StringTextAnalyzer+countWords(text: String) : Number+findOccurrences(text: String, term: String) : Number 在这个类图中,我们定义了一个StringHandler类,负责处理字符串的基本操作,如按照换行符分割字符串和去除多余空白。...
Use the `String.split()` method to split a string by newline, e.g. `str.split(/\r?\n/)`.
alert("String found."); } // Extract a portion of the string and store it in a new variable var sliceString = newString.slice(newString.indexOf("l")+2,newString.length); alert(sliceString); // The split function creates a new array containing each value separated by a space stringA...

line" // 两行字符串分别写在两行上: `the newline character at the end of this line is included literally in this string` 请注意,当使用单引号界定字符串时,必须小心处理英语缩写和所有格,例如can’t和O’Reilly’s。由于撇号与单引号字符相同,必须使用反斜杠字符(\)来“转义”出现在单引号字符串中的...

split() Break a string into an array of substrings. Example 1: Regular Expressions const string = 'Find me'; const pattern = /me/; // search if the pattern is in string variable const result1 = string.search(pattern); console.log(result1); // 5 // replace the character with anothe...

请注意,输入是多行的,因此首先您需要通过执行 var data = input.split('\n'); 将其拆分为多行。每次拆分都会为您提供中间有空格的字符串。因此,要获得单个字符,您必须再次拆分,但这次使用 var firstLine = data[0].split(' '); 类的空格。获得所有输入后,您就可以编写自己的算法了。请注意,我也留下了...
