字符统计

第一行一个正整数 ${T}$ ,代表测试数据的组数

第二行开始为第一组测试数据，测试数据每行不超过 ${1024}$ 个字符

每两组测试数据之间用连续的 ${5}$ 个 ${=}$ 分隔，保证测试数据中不会出现连续的 ${5}$ 个 ${=}$

2 This is a sample input. Hello World!! ===== The speech by Hunyak, translated, is: "What am I doing here? They say, the famous Hungarian police, that I held down my husband and chopped off his head. But I didn't do it, I am not guilty. I can't believe that Uncle Sam says I did it. They say I didit, but really I didn't."
