在 Julia 中获取字符串的重复 – repeat() 方法

repeat()是 julia 中的一个内置函数，用于返回一个字符串，该字符串是指定字符串在指定次数内的重复。

Syntax:
repeat(String::AbstractString, r::Integer)

Parameters:

• String: Specified string or character
• r::Integer: Specified number of times

Returns: It returns a string which is the repetition of specified string with specified number of times.

示例 1：

# Julia program to illustrate 
# the use of String repeat() method
  
# Create a repetition of string "gfg"
# with 3 times of repetition.
println(repeat("gfg", 3))
  
# Create a repetition of character "a"
# with 4 times of repetition.
println(repeat("a", 4))
  
# Create a repetition of string "Geeks"
# with 2 times of repetition.
println(repeat("Geeks", 2))
  
# Create a repetition of string "@#"
# with 3 times of repetition.
println(repeat("@#", 3))

输出：

gfggfggfg
aaaa
GeeksGeeks
@#@#@#

示例 2：

# Julia program to illustrate 
# the use of String repeat() method
   
# Create a repetition of string "123"
# with 3 times of repetition.
println(repeat("123", 3))
   
# Create a repetition of string "22"
# with 4 times of repetition.
println(repeat("22", 4))
   
# Create a repetition of string "03210"
# with 2 times of repetition
println(repeat("03210", 2))

输出：

123123123
22222222
0321003210
