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.
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.
Input: name = "alex", typed = "aaleex" Output: true Explanation: 'a' and 'e' in 'alex' were long pressed.
Input: name = "saeed", typed = "ssaaedd" Output: false Explanation: 'e' must have been pressed twice, but it wasn't in the typed output.
Input: name = "leelee", typed = "lleeelee" Output: true
Input: name = "laiden", typed = "laiden" Output: true Explanation: It's not necessary to long press any character.
1 <= name.length <= 1000
1 <= typed.length <= 1000

Solution in Python
from itertools import groupby class Solution: def isLongPressedName(self, name: str, typed: str) -> bool: groupName = [(x,len(list(y))) for x,y in (groupby(name))] groupTyped = [(x,len(list(y))) for x,y in (groupby(typed))] if len(groupName)!= len(groupTyped): return False for (a,b),(x,y) in zip(groupName,groupTyped): if not a==x or y<b: return False return True
