What is obtained when the result of passing 9 into function 4 is then passed into the function whose array index matches the result of passing 3 into function 2?

gistfile1.js

var puzzlers = [
  function ( a ) { return 8*a - 10; }, 
  function ( a ) { return (a-3) * (a-3) * (a-3); }, 
  function ( a ) { return a * a + 4; },
  function ( a ) { return a % 5; }
];

alert((puzzlers[(puzzlers[1])(3)])((puzzlers[3])(9)));
