Julia findnext()用法及代码示例

findnext() 是 julia 中的一个内置函数，用于返回从指定位置开始的指定字符串中指定模式的下一次出现。

用法:

findnext(pattern::AbstractString, string::AbstractString, start::Integer)

参数：

模式::抽象字符串:指定花样
字符串::抽象字符串:指定字符串
开始::整数：它是将要执行匹配的起始位置。

返回值：它返回从指定位置开始的指定字符串中指定模式的下一次出现。

范例1：

Python


# Julia program to illustrate
# the use of String findnext() method
  
# Here the pattern is "g", String is
# "geeks" and position is 1
Println(findnext("g", "geeks", 1))
 
# Here the pattern is "G", String is
# "GeeksforGeeks" and position is 6
Println(findnext("G", "GeeksforGeeks", 6))
 
# Here the pattern is "e", String is
# "GeeksforGeeks" and position is 5
Println(findnext("G", "GeeksforGeeks", 5))
 
# Here the pattern is "k", String is
# "GeeksforGeeks" and position is 2
Println(findnext("G", "GeeksforGeeks", 2))

输出：

# Here the pattern is "23", String is
# "12345" and position is 2
Println(findnext("23", "12345", 2))
 
# Here the pattern is "3", String is
# "12345" and position is 5
Println(findnext("3", "12345", 5))
 
# Here the pattern is "123", String is
# "123123123" and position is 4
Println(findnext("123", "123123123", 4))
