PYTHON

Given a 2D array with the layout of the floor of a concert hall and the height (in dwillyinches, a logarithmic measurement of height) of each concert attendee, write a program that determines if every attendee can see the front stage. An attendee can see the front stage if they are strickly taller than all of the attendees in front of them.

Everyone can see the front-stage in the example below:

# FRONT STAGE
[[1, 2, 3, 2, 1, 1],
[2, 4, 4, 3, 2, 2],
[5, 5, 5, 5, 4, 4],
[6, 6, 7, 6, 5, 5]]

# Starting from the left, the 6 > 5 > 2 > 1, so all four of these attendees can see.
# 6 > 5 > 4 > 2 - so all four of these attendees can see
# FRONT STAGE
[[1, 2, 3, 20, 1, 1], 
[2, 4, 4, 3, 2, 2], 
[5, 5, 5, 10, 4, 4], 
[6, 6, 7, 6, 5, 5]]

# The 10 is in front of the 6 and blocking its view; also the 20 blocks the 3, 10, and 6.

Your program should print True if every number (i.e., attendee) can see the front-stage, and False if even a single number/attendee cannot.
