• 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:

# n characters of the specified string
println(first("GeeksforGeeks", 0))
println(first("GeeksforGeeks", 5))
println(first("GeeksforGeeks", 8))
println(first("GeeksforGeeks", 10))
