Function readLineAndRemoveSpaceChar

executor/checker.go:21–29

通常情况下，我们定义Tab、换行和空格字符是"空白字符" Usually, tab, line break and white space are the special blank words, called 'SpaceChar' 使用IOReader读写每一行， 并移除空白字符

(buf *bufio.Reader)

// 使用IOReader读写每一行， 并移除空白字符
func readLineAndRemoveSpaceChar(buf *bufio.Reader) (string, error) {
	line, isContinue, err := buf.ReadLine()
	for isContinue && err == nil {
		var next []byte
		next, isContinue, err = buf.ReadLine()
		line = append(line, next...)
	}
	return removeSpaceChar(string(line)), err
}

// 移除空白字符
// Remove the special blank words in a string
