Easy interview question got harder: given numbers 1..100, find the missing number(s) given exactly k
...so need an algorithm for factorization over finite fields, for example the one by Berlekamp or Cantor-Zassenhaus.
High level pseudocode for constant k:
Compute i-th powers of given numbers
Subtract to get sums of i-th powers of unknown numbers. Call the sums bi.
Use Newton's identities to compute...

It's also possible to call hasOwnProperty through the object itself:
if (obj.hasOwnProperty(prop)) {

}
But this will fail if the object has an unrelated field with the ...

How does Java handle integer underflows and overflows and how would you check for it?
...can store larger values, e.g. long or maybe java.math.BigInteger. The last one doesn't overflow, practically, the available JVM memory is the limit.
