题解 | 输入整型数组和排序标识，对其元素按照升序或降序进行排序

N = int(input(''))
x = input('').split()
X = []
for i in x:
    X.append(int(i))
# 冒泡排序
def st(X, method):
    for i in range(N - 1):
        for j in range(N - 1 - i):
            if method == 0: # 升序
                if X[j] >= X[j + 1]:
                    y = X[j]
                    X[j] = X[j + 1]
                    X[j + 1] = y
            else: # 降序
                if X[j] <= X[j + 1]:
                    y = X[j]
                    X[j] = X[j + 1]
                    X[j + 1] = y
    return X
method =  int(input(''))
Y = ''
for y in st(X, method):
    Y += str(y) + ' '
print(Y[:-1])
