我是这里的新手,并且是Hackerrank。我正在尝试解决简单的数组和问题:
Given an array of integers, find the sum of its elements.
For example, if the array , , so return .
Function Description
Complete the simpleArraySum function in the editor below. It must return the sum of the array elements as an integer.
simpleArraySum has the following parameter(s):
ar: an array of integers
Input Format
The first line contains an integer, , denoting the size of the array.
The second line contains space-separated integers representing the array's elements.
Constraints
Output Format
Print the sum of the array's elements as a single integer.
我正在尝试找到解决方案,但到目前为止我找不到解决方案。它在jupyter笔记本上有效。它说:
Traceback (most recent call last):
File "Solution.py", line 34, in <module>
result = simpleArraySum(ar)
File "Solution.py", line 13, in simpleArraySum
amount=int(input())
EOFError: EOF when reading a line
在输出按钮上说'stdout没有响应。这是我的代码:
def simpleArraySum(ar):
#
# Write your code here.
#
amount=int(input())
nums=list(map(int,input().split()))
sums=0
for i in nums:
sums+=i
print(sums)
您可以这样做;
def sum_array(arr):
total = 0
for i in arr:
total += i
return total
您的代码存在一些问题。
请注意,有许多方法可以解决此问题,而无需编写您自己的自定义函数。
