1. Write a Python program to print all Perfect numbers between 1 to n. (Use any loop you want)

Perfect number is a positive integer which is equal to the sum of its proper positive divisors.

Proper divisors of 6 are 1, 2, 3.

Sum of its proper divisors = 1 + 2 + 3 = 6.

Hence 6 is a perfect number.

*** proper divisor means the remainder will be 0 when divided by that number.

Sample Input: n = 1000;

Sample Output: 6, 28, 496

```def divisors(n):
s = 1
for x in range(2,n):
if(n%x == 0):
s += x
return s

def isperfect(n):
if(divisors(n) == n):
return True
else:
return False

#Testing
def main():
n = int(input("n = "))
lst = []
for i in range(2,n+1):
if(isperfect(i)):
lst.append(i)
print(str(lst)[1:-1])

main()

```

```n = 1000
6, 28, 496

```

A positive integer is said to be a perfect number if it equals the sum of its positive divisors (excluding the number itself). As an example, 6 is aperfect number because its divisors, 1, 2, and 3 sum up to 6. The first four perfect numbers are 6, 28, 496, 8128.

Using the following functions, modify the Python program written for the perfect number into TDD Java program: 1) divisors (n) - takes a positive integer 'n' and return it's divisors sum as output. 2) isPerfect(n) - takes a positive integer 'n' as input and produces the result either as 'n is perfect' or 'n is not perfect using the function divisors()

C Programming Write a C program that asks the user for a positive number n (n ≥ 1) then, the program displays all the perfect numbers up to (including) n. A number n is said to be a perfect number if the sum of all its positive divisors (excluding itself) equals n. For example, the divisors of 6 (excluding 6 itself) are 1,2 and 3, and their sum equals 6, thus, 6 is a perfect number. Display the numbers with...

Please Write the task in c++ Task A perfect number is an integer that is equal to the sum of its divisors (where 1 is considered a divisor). For example, 6 is perfect because its divisors are 1, 2, and 3, and 1 + 2 + 3 is 6. Similarly, 28 is perfect because it equals 1 + 2 + 4 + 7 + 14.

Write a program that asks the user for a lower limit and an upper limit. The program finds all pairs of amicable numbers where the first number of the pair is between those limits. The second number of the pair may or may not be between the limits. To do this sensibly, write a function int sumDivisors( int num ); that returns the sum of all the proper divisors of num. The main program looks at each integer N between...
