Function Call Arity Check

Problem

Validate a function call's arguments against required and optional parameter names. Return 'missing' when any required name is absent, otherwise 'unexpected' when an argument is neither required nor optional, otherwise 'ok'.

Missing takes precedence over unexpected.

Hint

Check required presence first, then scan for unknown argument names.

Test cases

case 1

in: [["a","b"],["c"],{"a":1,"b":2}]

expected: "ok"

case 2

in: [["a","b"],["c"],{"a":1}]

expected: "missing"

case 3

in: [["a"],["b"],{"a":1,"b":2,"d":3}]

expected: "unexpected"

case 4

in: [[],[],{}]

expected: "ok"

case 5

in: [[],["x"],{"y":1}]

expected: "unexpected"

case 6

in: [["a"],["b"],{"b":1}]

expected: "missing"
