按列计算两个数组的最大值，并计算一个数组具有最大值的次数

def calculate_max_value_and_count(array_a, array_b):
    max_value = float("-inf")
    count_a = 0
    count_b = 0
    
    for i in range(len(array_a)):
        if array_a[i] > max_value:
            max_value = array_a[i]
            count_a = 1
        elif array_a[i] == max_value:
            count_a += 1
            
        if array_b[i] > max_value:
            max_value = array_b[i]
            count_b = 1
        elif array_b[i] == max_value:
            count_b += 1
    
    return max_value, count_a if count_a > count_b else count_b

# 测试
array_a = [1, 2, 3, 4, 5]
array_b = [5, 4, 3, 2, 1]

max_value, max_count = calculate_max_value_and_count(array_a, array_b)

print("最大值:", max_value)
print("最大值出现的次数:", max_count)
