在 Python 中对字谜进行分组
pythonserver side programmingprogramming更新于 2025/10/25 18:20:17
假设我们有一组字符串。我们必须将字谜分组在一起。因此,如果 ["eat", "tea", "tan", "ate", "nat", "bat"],则组为 [["ate","eat","tea"],["nat","tan"],["bat"]]
要解决这个问题,我们将遵循以下步骤 −
- 将 res 定义为 map
- for i in string array
- x := x and join, sorted string of i
- if x in result
- insert i in result[x]
- else result[x] := [i]
- 以列表形式返回 res 的值
示例 (Python)
让我们看下面的实现,以便更好地理解 −
class Solution:
def groupAnagrams(self, strs):
result = {}
for i in strs:
x = "".join(sorted(i))
if x in result:
result[x].append(i)
else:
result[x] = [i]
return list(result.values())
ob1 = Solution()
print(ob1.groupAnagrams(["eat", "tea", "tan", "ate", "nat", "bat"]))
输入
["eat", "tea", "tan", "ate", "nat", "bat"]
输出
[["ate","eat","tea"],["nat","tan"],["bat"]]
