IN JAVA

Define a function pairup that takes as input two equal-length lists A and B and return a list with the corresponding paired-up elements.

Example:

pairup([1;2;3],["a"; "b"; "c"]);;

val it : (int * string) list = [(1, "a"); (2, "b"); (3, c")]

Do not read input, instead use the arguments to the function. Do not print the output, instead return values as specified.
