Gloomy day in a school, we had an activity called arranging cups from smallest to biggest. We have given cups in random order, size varies from 1 to 10.
Cups initial arrangement is like these numbers are their size
7 5 3 2 4 1 6 10 9 8 and position considered from 1 to 10
Certain rules were set to make you a winner.
- You should be able to do that in 5 exchanges.
- The time limit was 5 minutes (300 seconds).
- Should be the first one to complete.
Below things don’t make you a winner
- If you complete it first and take more than 5 exchanges to complete, it will not make you a winner.
How will you approach it?
This is exactly how I solved, made me the winner
I glanced at all the cups for 10 seconds. And used the below technique in 5 steps
Step 1: Exchanged cup in position 8 with a cup in position 10
Step 2: Exchanged cup in position 6 with position 7
Step 3: Exchanged cup in position 4th with position 5
Step 4: Exchanged cup in position 1 with position 7
Step 5: Exchanged cup in position 2 with position 5
I was able to apply the above logic in 5 minutes and made me the winner
