Write a program to check the given number is perfect or not ?Constraints:1<n<1000Input FormatAn integer nOutput FormatA corresponding stringExample:Input 1:6Output 1:YesInput 2:3Output 2:No Explanation:Sum of factors of the given number must be equal to the numberFactors of 6 are 1,2,3 . 1+2+3=6 which is equal to the given number. So 6 is a perfect number

Sure, here is a Python program that checks if a number is perfect or not:

def is_perfect(n):
    sum = 1
    i = 2
    while i * i <= n:
        if n % i:
            i += 1
        else:
            if i * (n // i) == n:
                sum = sum + i + n//i
            else:
                sum = sum + i
            i += 1
    return sum == n and n!=1

n = int(input("Enter a number: "))
if is_perfect(n):
    print("Yes")
else:
    print("No")

This program works by finding all the divisors of the number and adding them up. If the sum of the divisors (excluding the number itself) is equal to the number, then the number is perfect.

Sure, here is a Python program that checks if a number is perfect or not:

def is_perfect(n):
    sum = 1
    i = 2
    while i * i <= n:
        if n % i:
            i += 1
        else:
            if i * (n // i) == n:
                sum = sum + i + n//i
            else:
                sum = sum + i
            i += 1
    return sum == n and n!=1

# Test the function
n = int(input("Enter a number: "))
print("Yes" if is_perfect(n) else "No")

This program works by finding all the divisors of the number and adding them up. If the sum equals the original number, then the number is perfect. The function is_perfect(n) checks if a number n is perfect or not. The while loop inside the function is used to find the divisors of n. If n is divisible by i, then both i and n//i are divisors of n. The sum of the divisors is kept in the variable sum. If sum equals n and n is not 1, then n is a perfect number. The input() function is used to take the number to be checked from the user. The result is printed out using the print() function. If the number is perfect, "Yes" is printed, otherwise "No" is printed.
