LeetCode - Strings - Check If a String Can Break Another String 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). 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 class Solution { public boolean checkIfCanBreak(String s1, String s2) { if(s1.equals(s2)) return true; char[] s1_arr = s1.toCharArray(); char[] s2_arr = s2.toCharArray(); Arrays.sort(s1_arr); Arrays.sort(s2_arr); boolean result1 = true; boolean result2 = true; for(int i=0;i<s1_arr.length;i++){ if(s1_arr[i]<s2_arr[i]){ result1=false; break; } } for(int i=0;i<s2_arr.length;i++){ if(s2_arr[i]<s1_arr[i]){ result2=false; break; } } return (result1 || result2); } }
