Write a Python program to sum all amicable numbers from 1 to specified numbers. Note: Amicable numbers are two different numbers so related that the sum of the proper divisors of each is equal to the other number. (A proper divisor of a number is a positive factor of that number other t...
9. Write a Python program to find three numbers from an array such that the sum of three numbers equal to zero. Input : [-1,0,1,2,-1,-4] Output : [[-1, -1, 2], [-1, 0, 1]] Note : Find the unique triplets in the array. Click me to see the sample solution...

Upon execution, the above program returns false, as set "b" is not a subset of "a". False Here, we have two programs in both we have used issubset() method to check if "a" and "b" are subset of each other. Since all element of "a" are present in "b". so, output comes...
然后,我们定义了一个名为find_amicable_numbers的函数,用于找出整数n以内的全部亲密数。该函数通过遍历从2到n-1之间的数,对于每个数,先计算其真因子之和sum1,然后判断sum1是否大于该数,并且sum1的真因子之和是否等于该数。如果满足条件,则将该数和sum1的组合添加到列表amicable_numbers中。最后,返回列表amicable_...
