Get a substring of specific size from starting of a string in Julia – first() Method
The first()
is an inbuilt function in julia which is used to return a string consisting of the first n characters of the specified string, where n will be passed as parameter.
Syntax:
first(s::AbstractString, n::Integer)Parameters:
- s::AbstractString: Specified string.
- n::Integer: Specified integer value.
Returns: It returns a string consisting of the first n characters of the specified string, where n will be passed as parameter.
Example 1:
# Julia program to illustrate # the use of String first() method # Getting a string consisting of the first # n characters of the specified string println(first( "w3wiki" , 0 )) println(first( "w3wiki" , 5 )) println(first( "w3wiki" , 8 )) println(first( "w3wiki" , 10 )) |
Output:
Example 2:
# Julia program to illustrate # the use of String first() method # Getting a string consisting of the first # n characters of the specified string println(first( "1 + 2+3 + 4" , 0 )) println(first( "2-4-6-8" , 4 )) println(first( "1 * 3*5 * 7" , 6 )) |
Output:
