一个含有字符串的数组，例如:["a","b","a","c","b","d","a",1,1],需要得到一个新数组 ["a1","b1","a2","c","b2","d","a3","11","12"]

以下是 Python 代码实现：

arr = ["a","b","a","c","b","d","a",1,1]
new_arr = []
count_dict = {}

for item in arr:
    if isinstance(item, str):
        if item not in count_dict:
            count_dict[item] = 1
            new_arr.append(item + str(count_dict[item]))
        else:
            count_dict[item] += 1
            new_arr.append(item + str(count_dict[item]))
    else:
        if item not in count_dict:
            count_dict[item] = 1
            new_arr.append(str(item) + str(count_dict[item]))
        else:
            count_dict[item] += 1
            new_arr.append(str(item) + str(count_dict[item]))

print(new_arr)

输出结果为：`['a1', 'b1', 'a2', 'c1', 'b2', 'd1', 'a3', '11', '12']`
