Arrays - Find missing numbers in a Sequence

Question

I\'m trying to find an easy way to loop (iterate) over an array to find all the missing numbers in a sequence, the array will look a bit like the one below.

var nu

Answer 1

Watch your leading zeroes, they will be dropped when the array is interpreted-

var A= [0189459, 0189460, 0189461, 0189463, 0189465]

(A returns [189459,189460,189461,189463,189465])

function absent(arr){
    var mia= [], min= Math.min.apply('',arr), max= Math.max.apply('',arr);
    while(min

var A= [0189459, 0189460, 0189461, 0189463, 0189465]; alert(absent(A))

/* returned value: (Array) 189462,189464 */
