Given a strings, returnthe number of substrings that have only one distinct letter. Example 1: Input: s = "aaaba" Output: 8 Explanation: The substrings with one distinct letter are "aaa", "aa", "a", "b". "aaa"
Given a stringS, return the number of substrings that have only one distinct letter. Example 1: Input: S = "aaaba" Output: 8 Explanation: The substrings with one distinct letter are "aaa", "aa", "a", "b". "aaa" occurs 1 time. "aa" occurs 2 times. "a" occurs 4 times. "b"...

当指定distinct时,不能接order_by_clause: 如果指定表达式,count返回表达式不为空的值: 当指定*号时,它返回所有行,含重复行和空值.count从不返回null: count(*) 与 count(1) 执行结果相同,但1并不是指第一列.列名为参数时,查的是不含NULL值的行数: Aggregate Examples (聚合) -- 含重复行和空值,所有行...
