查找数组的模式？

def findArrayPattern(arr):
    pattern = []
    count = {}
    
    # 遍历数组，统计元素出现的次数
    for num in arr:
        if num in count:
            count[num] += 1
        else:
            count[num] = 1
    
    # 遍历哈希表，找到重复出现的模式
    for num, freq in count.items():
        if freq > 1:
            pattern.append(num)
    
    return pattern

# 示例用法
arr = [1, 2, 3, 4, 5, 2, 3, 4, 5, 6]
result = findArrayPattern(arr)
print("重复出现的模式：", result)
