1. Program to Print Armstrong Numbers in a Given Range

An Armstrong number is a number whose sum of cubes of digits is equal to the number itself. Example: 370 = 3³ + 7³ + 0³

start = int(input("Enter start range: "))
end = int(input("Enter end range: "))

for num in range(start, end+1):
    temp = num
    s = 0
    while temp > 0:
        d = temp % 10
        s += d ** 3
        temp //= 10
    if s == num:
        print(num)
