Challenge 2 - solved in 334 seconds on a 50g

According to my program, the 1429th number is 604661760

(1427: 600000000
1428: 603979776
1429: 604661760
1430: 607500000)

Execution time: 5 minutes and 34 seconds (50g). The first number put on the stack in the program (smax) has to be changed to 29. The last number found was 1062882000 (number 1544). The 1545th number would be then 2^30 = 1073741824
