Leetcode - Check If a String Can Break Another String Solution
Given two strings: s1
and s2
with the same size, check if some permutation of string s1
can break some permutation of string s2
or vice-versa. In other words s2
can break s1
or vice-versa.
A string x
can break string y
(both of size n
) if x[i] >= y[i]
(in alphabetical order) for all i
between 0
and n-1
.
Example 1:
Input: s1 = "abc", s2 = "xya"
Output: true
Explanation: "ayx" is a permutation of s2="xya" which can break to string "abc" which is a permutation of s1="abc".
Example 2:
Input: s1 = "abe", s2 = "acd"
Output: false
Explanation: All permutations for s1="abe" are: "abe", "aeb", "bae", "bea", "eab" and "eba" and all permutation for s2="acd" are: "acd", "adc", "cad", "cda", "dac" and "dca". However, there is not any permutation from s1 which can break some permutation from s2 and vice-versa.
Example 3:
Input: s1 = "leetcodee", s2 = "interview"
Output: true
Constraints:
s1.length == n
s2.length == n
1 <= n <= 10^5
- All strings consist of lowercase English letters.
Solution in Python
class Solution:
def checkIfCanBreak(self, s1: str, s2: str) -> bool:
s1 = sorted(s1)
s2 = sorted(s2)
return all((x<=y for x,y in zip(s1,s2))) or all((x<=y for x,y in zip(s2,s1)))
