如何在一个数组中找出行中多少次是相同的值？

def count_same_values(arr):
    count_dict = {}  # 创建空的哈希表
    for num in arr:
        if num in count_dict:
            count_dict[num] += 1
        else:
            count_dict[num] = 1
    same_values_count = 0
    for count in count_dict.values():
        if count > 1:
            same_values_count += 1
    return same_values_count

# 示例用法
array = [1, 2, 3, 4, 2, 3, 4, 4, 5]
result = count_same_values(array)
print("数组中相同值的次数为:", result)
