Since it’s a large venue, they do help you identify where you are by the color of the carpet: Red = Delta, Conservatory = green, Magnolia = yellow. You can even tell which wing you’re in:
Back in the day I did it with the old IBM mechanical keyboards but those things were tanks. I wouldn’t of imagined a modern membrane keyboard would survive and mechanicals are too expensive to experiment.
def bubbleSort(arr):
n = len(arr)
# optimize code, so if the array is already sorted, it doesn't need
# to go through the entire process
# Traverse through all array elements
for i in range(n-1):
# range(n) also work but outer loop will
# repeat one time more than needed.
# Last i elements are already in place
swapped = False
for j in range(0, n-i-1):
# traverse the array from 0 to n-i-1
# Swap if the element found is greater
# than the next element
if arr[j] > arr[j + 1]:
swapped = True
arr[j], arr[j + 1] = arr[j + 1], arr[j]
if not swapped:
# if we haven't needed to make a single swap, we
# can just exit the main loop.
return
# Driver code to test above
arr = [64, 34, 25, 12, 22, 11, 90]

print("Sorted array is:")
for i in range(len(arr)):
print("% d" % arr[i], end=" ")
What I didn’t realize at Insights 2022 is they have the same room numbers in each wing. Spent about 5 minutes trying my key before a terrified person from the other side of the door informed me I was probably in the wrong wing.
