Course Introduction：A square pyramid number is the sum of the squares of natural numbers. Natural numbers include all numbers from 1 to infinity. For example, the first 4 square pyramid numbers are 1, 5, 14, and 30. To understand better, consider the following fact: If we start with a square pyramid of numbers and stack the number balls in descending order, they will form a pyramid. Problem Statement Given a number Sum. If Sum is the sum of the squares of the first n natural numbers, return n, otherwise return false. The translation of Example1 is: Example 1Input=30Output=4Explanation=30 is the sum of the squares of the first 4 natural numbers. 1*1+2*2+3*3+4*4=30. Therefore, the output should be 4. Ex

Course Introduction：The average of the squares of natural numbers is calculated by adding all the squares of n natural numbers and then dividing by that number. The first two natural numbers in the example are 2.5, 12+22=5=>5/2=2.5. There are two methods of calculation in programming - Using loops Using formulas Calculating the average of squares of natural numbers using loops This logic works by finding the squares of all natural numbers. Find the square of each by looping from 1 to n and add to the sum variable. Then divide that sum by n. Program to calculate the sum of squares of natural numbers - sample code real-time demonstration #include<stdio.h>intmain(){ intn=2;
