在python中查找N个自然数列表中的缺失数

Question

查找N个自然数列表中缺少的元素。 [第10行和第18行出错][“int”对象不可调用]

numTest = int(input(""))
n = 1
while n <= numTest:
    numEle = int(input(""))

    numEleList = list(map(int, input("").split()))


    def fun(numEleList, numEle):
        sumReq = int((numEle(numEle + 1)) / 2)
        sumGiven = sum(numEleList)

        reqNum = sumReq - sumGiven

        return reqNum


    print(fun(numEleList, numEle))

    n += 1

Answer 1

你忘了*

line 10: numEle * (numEle + 1) / 2
