Problem 1(Multiples of 3 and 5) If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below 1000. In Python: sum=0 for i in range(1,1000): if i%3==0 or i%5==0: sum+=i print(sum) Run time: 0.00024700164794921875 seconds In Python:print(sum([i for i in range(1, 1000) if i % 3 == ..
