Running Total of Integer Squares

Write a Python program to round each float in a given list of numbers up to the next integer and return the running total of the integer squares.

Input:  
[2.6, 3.5, 6.7, 2.3, 5.6]
Output:
[9, 25, 74, 83, 119]

Input:  
[301.1, 401.4, -23.1, 13554122.0, 10201.0101, 10000000.0]
Output:
[91204, 252808, 253337, 183714223444221, 183714327525025, 283714327525025]

Sample Solution:

Python Code:

# License: https://bit.ly/3oLErEI

# Import the 'ceil' function from the 'math' module
from math import ceil

# Define a function named 'test' that takes a list of numbers as input
def test(nums):
    # Initialize an empty list to store the running total of integer squares
    running_squares = []
    
    # Initialize a variable 'tot' to store the running total
    tot = 0
    
    # Iterate over each value 'v' in the input list 'nums'
    for v in nums:
        # Add the square of the ceiling of 'v' to the running total
        tot += ceil(v) ** 2
        
        # Append the current running total to the 'running_squares' list
        running_squares.append(tot)
    
    # Return the list of running totals
    return running_squares

# Example 1
nums1 = [2.6, 3.5, 6.7, 2.3, 5.6]
print("List of numbers:", nums1)
print("Round each float of the said list up to the next integer and return the running total of the integer squares:")
print(test(nums1))

# Example 2
nums2 = [301.1, 401.4, -23.1, 13554122.0, 10201.0101, 10000000.0]
print("\nList of numbers:", nums2)
print("Round each float of the said list up to the next integer and return the running total of the integer squares:")
print(test(nums2))

Sample Output:

List of numbers: [2.6, 3.5, 6.7, 2.3, 5.6]
Round each float of the said list up to the next integer and return the running total of the integer squares:
[9, 25, 74, 83, 119]

List of numbers: [301.1, 401.4, -23.1, 13554122.0, 10201.0101, 10000000.0]
Round each float of the said list up to the next integer and return the running total of the integer squares:
[91204, 252808, 253337, 183714223444221, 183714327525025, 283714327525025]

• Write a Python program to round up each float in a list to the next integer, square it, and compute the running total of these squares.
• Write a Python program to use math.ceil() on each element of a list, square the result, and generate a cumulative sum list.
• Write a Python program to iterate over a list of floats, round them up, square them, and produce a list of running totals.
• Write a Python program to use list comprehension to create a new list of squared ceiling values, then compute their cumulative sum.
