How do I compare string in Ocaml

Question

How do I go about comparing strings? For example "a" and "b", since "a" comes before "b" then I would put in a tuple like this("a","b"). For "c" and "b", it would be like this ("b","c")

Answer 1

You can compare strings with the usal comparison operators: =, <>, <, <=, >, >=.

You can also use the compare function, which returns -1 if the first string is less than the second, 1 if the first string is greater than the second, and 0 if they are equal.

# "a" < "b";;
- : bool = true
# "a" > "b";;
- : bool = false
# compare "a" "b";;
- : int = -1
