### Senior Applications Developer at Deutsche Bank was asked...

 We have a pond containing a single bacterium. The number of bacteria double every 5 minutes, and the pond is full of them in 24 hours. If we started with the same pond but two bacteria, how long will it take to fill the pond?4 AnswersI struggled with this a bit and got close. I believe answer is: 23:55This is a clear case of Geometric progression. Find the nth term Tn1 = a*r^(n-1). where n = (24 * 60)/5,a = 1 and r=2. when the initial value (a) = 2, the values become n = ?, a = 2 and r = 2. Since Tn1 = Tn2, Equate the RHS of both the equation. Since the base are equal, equate the powers, doing so will give the n value. When n is convert into minutes one get 23 hrs 55 minutes.this is easy, you don't need all the math. The pond was half full five minutes before, so it's 23:55Show More ResponsesThe first pond started with 1 bacterium and doubled to 2 in five minutes. Therefore, the second pond will take 5 minutes less than the first to be full. ie: 23:55

 There are 10 stacks of 10 coins each. 9 of the stacks contain coins that weigh 1g each. The other stack contains coins of 2g each. The coins look the same. We have a scale that we can get a measurement of grams from, not a balance. We can use the scale exactly once to weigh anything here from a single coin to all of them. How can we determine which stack is the 2g coins?4 AnswersWeigh these together: 10 coins from stack 1, 9 from stack 2, etc ending with 1 from stack 10. The weight of these will tell you which stack has the 2g coins. Ex: if it's 1st stack: 65g, 2nd: 64g, 10th: 54gExcellent question!A more eloquent answer would be: Weigh together 1 coin from stack 1, 2 coins from stack2, 3 coins from stack 3, etc. Subtract 55 from that total weight to get the number of the stack with the 2g coins.Show More ResponsesBinary sort 1. Use single coin (I'd drop my stacks *s*) from each stack. Mark them by stack. 2. Place 5 each on both scales; note lower scale. 3. Place 2 coins on each scale, keep one aside; note scale. 4. If scales are at same level the coin NOT on the scale indicates the stack with heavier coins. Done. 5. If one scale is lower place 1 coin on each scale, note lower, identify stack. Done.

### Mainframe Applications Development Manager/Senior Developer at J.P. Morgan was asked...

Mar 19, 2009
 How would you bypass change management processes to dynamically change OS JCL streams?2 AnswersYou would need to establish a baseline set of JCL procedures and identify the parameters which could change depending on the run time requirements. The domain values for all variables would need to be stored in DB2 table or a VSAM indexed file and a Stored Procedure or REXX script would need to determine what variables were required for a particular run and obtain them from the VSAM or DB2 datastore. These parameters would need to overlaid onto the templatge JCL and the resulting JCL stream would need to be submitted via the internal reader. The feasibility of this would depend on the scheduling software in use on the mainframe LPAR.This may be too simple of an answer, but I would have answered the question by saying I would do this as a global change.

 Having to recite some silly technical reference that I never use to build web applications in .NET. Some of the participants usually from India will just grab a question from a text book.That would be OK if I were in school and reading chapters from that book preparing for an exam or quiz.1 AnswerI do not memorize the reference manuals. I research if I need to and sometimes use the professional community groups when I need them.
