The cmp() is an inbuilt function in julia which is used to return 0 if the both specified strings are having the same length and the character at each index is the same in both strings, return -1 if a is a prefix of b, or if a comes before b in alphabetical order and return 1 if b is a prefix of a, or if b comes before a in alphabetical order.
Syntax:
cmp(a::AbstractString, b::AbstractString)Parameters:
- a::AbstractString: Specified first string
- b::AbstractString: Specified second string
Returns: It returns 0 if the both specified strings are having the same length and the character at each index is the same in both strings, return -1 if a is a prefix of b, or if a comes before b in alphabetical order and return 1 if b is a prefix of a, or if b comes before a in alphabetical order.
Example 1:
# Julia program to illustrate # the use of String cmp() method # Comparing two strings and # getting the values 0, -1 or 1 println(cmp("abc", "abc"))
println(cmp("a", "b"))
println(cmp("c", "b"))
println(cmp("ab", "abc"))
println(cmp("abc", "ab"))
println(cmp("ab", "ac"))
|
Output:
0 -1 1 -1 1 -1
Example 2:
# Julia program to illustrate # the use of String cmp() method # Comparing two strings and # getting the values 0, -1 or 1 println(cmp("1", "2"))
println(cmp("1", "1"))
println(cmp("12", "21"))
println(cmp("123", "23"))
println(cmp("31", "23"))
|
Output:
-1 0 -1 -1 1
