Solution 1
The text you provided seems to be a question about implementing a tail-recursive function in Python to calculate the sum of squares of the first n natural numbers. However, the question is not clear and the provided code snippets are for calculating factorial, not the sum of squares.
Here is a Python function that uses tail recursion and an accumulator to calculate the sum of squares of the first n natural numbers:
def sum_of_squares(n, acc=0):
if n == 0:
return acc
else:
return sum_of_squares(n-1, acc + n**2)
In this function, n is the number up to which you want to calculate the sum of squares, and acc is the accumulator that keeps the running total of the sum of squares. The function calls itself until n becomes 0, at which point it returns the accumulated total.

Problem StatementErin, a mathematician wants to calculate the sum of squares of the first n Triangular numbers. Write a recursive function called TotalSumOfSquares to help Erin that takes the input for n and outputs the sum of squares of the first n Triangular numbers.The formula to calculate the nth Triangular number is Tn = (n * (n+1)) / 2.ExampleIf n=4, the calculations are as follows:T1 = (1 * (1+1)) / 2 = 1T2 = (2* (2+1)) / 2 = 3T3 = (3 * (3+1)) / 2 = 6T4 = (4 * (4+1)) / 2 = 5So the sum of squares of first 4 triangular numbers = 12 + 32 + 62 + 52 = 1 + 9 + 36 + 100 = 146Input format :The input consists of an integer n, representing the number of triangular numbers to consider.Output format :The output prints an integer representing the sum of squares of the first n Triangular numbers.Refer to the sample output for the formatting specifications.Code constraints :In the given scenario, the test cases fall under the following constraints:1 ≤ n ≤ 50Sample test cases :Input 1 :4Output 1 :146Input 2 :29Output 2 :1212751
