数组中值的顶级计数循环

# 定义一个数组
arr = [1, 2, 3, 1, 2, 3, 1, 2, 3, 4, 4, 4]

# 创建一个字典来统计每个值的出现次数
count_dict = {}

# 遍历数组并统计值的出现次数
for num in arr:
    if num in count_dict:
        count_dict[num] += 1
    else:
        count_dict[num] = 1

# 找出出现次数最多的值
max_count = 0
max_value = None
for key, value in count_dict.items():
    if value > max_count:
        max_count = value
        max_value = key

print("出现次数最多的值是：", max_value)
print("出现次数：", max_count)
