What contestant has won the most number of challenges? Select their row from the castaway_details DataFrame and save this as Q11. This should return a DataFrame and the index and missing values should be left as is.

Answer 1

To find the contestant who has won the most number of challenges, we need to calculate the sum of challenges won for each contestant and then select the row with the highest sum.

Here's how you can do it:

``` python
# Calculate the sum of challenges won for each contestant
challenges_won = castaway_details[['Name', 'Individual Challenges Won', 'Team Challenges Won', 'Total Challenges Won']]
challenges_won['Total Challenges Won'] = challenges_won['Individual Challenges Won'] + challenges_won['Team Challenges Won']

# Select the row with the highest sum of challenges won
Q11 = challenges_won.loc[challenges_won['Total Challenges Won'].idxmax()]

# Print the result
print(Q11)
```

This will print the row of the contestant who has won the most number of challenges. Note that `castaway_details` is the name of the DataFrame containing all the details of the castaways.
