/* They claimed this fails. I disagreed. They apologized. Glad I didn't work there.

Purpose:
* Write 1 function for calls:
* sum(1,2)
* sum([1,2])
* sum(1)(2)
* Return:
* 1 int, either number or String or primitive type

function sum() {
switch(arguments.length) {
case(1):
if(typeof(arguments[0])=="number") {
var tmpsum = arguments[0];
function tmpf(a) {
tmpsum += a;
return tmpf;
}
tmpf.toString = function(){ return tmpsum; }
return tmp_f;

else
if(Array.isArray(arguments[0])) {
return arguments[0][0]+arguments[0][1];
