# 自己第一遍想出来的答案😂，比较水
n = int(input())
a = list(map(int, input().split()))
s = 0

for i in a:
    sum = 0
    for t in a[:s]:
        if t < i:
            sum += 1
    s += 1
    print(f"{sum} ", end="")


# AI 答案：
n = int(input())
a = list(map(int, input().split()))

for i in range(len(a)):
    print(f"{sum(1 for t in a[:i] if t < a[i])} ", end="")
