3.1.2.14 LAB: Essentials of the while loop
LAB
Estimated time
20-30 minutes
Level of difficulty

Objectives
Familiarize the student with:
- using the
whileloop; - finding the proper implementation of verbally defined rules;
- reflecting real-life situations in computer code.
Scenario
Listen to this story: a boy and his father, a computer programmer, are playing with wooden blocks. They are building a pyramid.
Their pyramid is a bit weird, as it is actually a pyramid-shaped wall - it's flat. The pyramid is stacked according to one simple principle: each lower layer contains one block more than the layer above.
The figure illustrates the rule used by the builders:
Your task is to write a program which reads the number of blocks the builders have, and outputs the height of the pyramid that can be built using these blocks.
Note: the height is measured by the number of fully completed layers - if the builders don't have a sufficient number of blocks and cannot complete the next layer, they finish their work immediately.
Test your code using the data we've provided.
Test Data
Sample input:
6
Expected output:
The height of the pyramid: 3
Sample input:
20
Expected output:
The height of the pyramid: 5
Sample input:
1000
Expected output:
The height of the pyramid: 44
Sample input:
2
Expected output:
The height of the pyramid: 1
blocks = int(input("Enter the number of blocks: "))
ReplyDeleteheight = 0
layers = 1
while layers <= blocks:
height += 1
blocks -= layers
layers += 1
print("The height of the pyramid:", height)
thx buddy
Deleteblocks = int(input("Enter the number of blocks: "))
Deleteheight=0
i=2
layer=1
while layer<=blocks:
layer=i+layer
height+=1
i+=1
print("The height of the pyramid:", height)
thank you
