이렇게 풀어도 되는지 모르겠습니다

import sys
sys.stdin=open("input.txt","rt")

n=int(input())
ls=list(map(int, input().split()))
res=[0]*n
for i in range(n):
    check = ls[i]
    count = 0  
    for j in range(n):
        if res[j] == 0:
            if count == check:
                res[j] = i + 1
                break
            else:
                count += 1
       
for x in res:
    print(x, end=" ")
