The problem requires determining the number of samples when the "done" flag is set. The data provided includes each person’s net worth and a flag indicating whether they have been done. The key steps to solving this problem are as follows:
-
Understanding the Flag: The "done" flag indicates whether a person’s net worth has been recorded. When the flag is set, the person’s net worth is recorded.
-
Total Samples Calculation: Each time a person’s net worth is recorded, it counts as a sample. When the "done" flag is set, each person’s net worth is recorded, ensuring their contributions to the total number of samples.
-
Key Insight: The initial data set does not have any recorded net worths when the "done" flag is set. As each person’s net worth is recorded and set to zero, the total number of samples remains zero.
- Conclusion: The total number of samples remains zero because the net worths are set to zero whenever the "done" flag is not active.
Final Answer
