처음 접근한 방법(틀린 이유를 모르겠음)

time= []
times=[]
sum=0
sum_=0

people=int(input(''))

time= input().split()


    
time_ = sorted(time)



for i in time_:
    sum=sum+int(i)
    times.append(sum)


for i in range(0,people):
    sum_+=times[i]
    
print(sum_)
    

 

+map

 

map(함수, <literable object>)

 

->함수를 각 객체에 적용시켜줌
