这次我试图使用 python 获得最大的成对产品,某些方面的概念对我来说仍然是新的。我继续得到列表索引越界错误和计算器溢出,鉴于我无法在 Python 中选择类型,我不知道如何处理。
我查看了 enumerate 和其他 iterate(ble) 函数,但无济于事。Id 回答这可以帮助未来的人在从 C 迁移到 python 时解决简单的 for 循环问题。
def max_pairwise_product(numbers):
n = len(numbers)
max_product = 0
for first in range(n):
for second in range(first + 1, n):
max_product = max(max_product,
numbers[first] * numbers[second])
return max_product
def max_pairwise_product_fast(numbers):
n = len(numbers)
index1 = 1
for i in range(2,n,1):
if (numbers[i]>numbers[index1]):
index1 = i
if (index1 == 1):
index2 = 2
else:
index2=1
for i in range(1,n):
if(numbers[i]!=numbers[index1] and numbers[i]>numbers[index2]):
index2 = i
return (numbers[index1]*numbers[index2])
if __name__ == '__main__':
input_n = int(input())
input_numbers = [int(x) for x in input().split()]
print(max_pairwise_product_fast(input_numbers))
