Your friend is typing his name into a keyboard. Sometimes, when typing a character c, the key might get long pressed, and the character will be typed 1 or more times.

\n\n

You examine the typed characters of the keyboard. Return True if it is possible that it was your friends name, with some characters (possibly none) being long pressed.

\n\n

 

\n

Example 1:

\n\n
\nInput: name = "alex", typed = "aaleex"\nOutput: true\nExplanation: 'a' and 'e' in 'alex' were long pressed.\n
\n\n

Example 2:

\n\n
\nInput: name = "saeed", typed = "ssaaedd"\nOutput: false\nExplanation: 'e' must have been pressed twice, but it was not in the typed output.\n
\n\n

 

\n

Constraints:

\n\n\n", "translatedTitle": "长按键入", "translatedContent": "

你的朋友正在使用键盘输入他的名字 name。偶尔,在键入字符 c 时,按键可能会被长按,而字符可能被输入 1 次或多次。

\n\n

你将会检查键盘输入的字符 typed。如果它对应的可能是你的朋友的名字(其中一些字符可能被长按),那么就返回 True

\n\n

 

\n\n

示例 1:

\n\n
\n输入:name = \"alex\", typed = \"aaleex\"\n输出:true\n解释:'alex' 中的 'a' 和 'e' 被长按。\n
\n\n

示例 2:

\n\n
\n输入:name = \"saeed\", typed = \"ssaaedd\"\n输出:false\n解释:'e' 一定需要被键入两次,但在 typed 的输出中不是这样。\n
\n\n
