Input:
Step I:
Step II:
These steps get repeated thereafter. In how many steps would the following input be fully arranged?
Input: 689, 722, 382, 184, 87, 67, 542, 326, 192
Options
- AV
- BVI
- CVII
- DVIII
Correct answer
B. VI
Step-by-step solution
Here the rule followed is the numbers are getting arranged in descending order.
Step I: The largest of the given numbers interchanges its place with the first number. [In case the largest number is already arranged, the second largest is interchanged with the number next to the largest and so on.]
Step II: The same process as that of step I will happen here but in this step, nos. will be shifted rightwards instead of interchange.
