Solution
Sure! To solve this problem using list comprehensions, we can follow these steps:
-
Read the four integers,
x,y,z, andn, from the input. -
Create a list comprehension to generate all possible coordinates on a 3D grid. The syntax for the list comprehension will be
[ [i, j, k] for i in range(x+1) for j in range(y+1) for k in range(z+1) ]. -
Add a condition to the list comprehension to filter out the coordinates whose sum is equal to
n. The condition will beif i + j + k != n. -
Print the resulting list of coordinates.
Here's the code that implements the above steps:
# Step 1
x = int(input())
y = int(input())
z = int(input())
n = int(input())
# Step 2 and 3
coordinates = [[i, j, k] for i in range(x+1) for j in range(y+1) for k in range(z+1) if i + j + k != n]
# Step 4
print(coordinates)
This code will generate and print a list of all possible coordinates on a 3D grid where the sum of the coordinates is not equal to n.
