Simple solution using Java with explanation
If the sting is of length 1, return ""\nIf all the elements in the string are \'a\' then replace the last one with \'b\' else repalce the first non \'a\' member
If the sting is of length 1, return ""\nIf all the elements in the string are \'a\' then replace the last one with \'b\' else repalce the first non \'a\' member with an \'a\'\n```\nclass Solution {\n    public String breakPalindrome(String palindrome) {\n        String s = palindrome;\n        if(s.length() == 1){\n            return "";\n        }\n        int i = 0, j = s.length() -  1;\n        char[] arr = s.toCharArray();\n        while(i < j){\n            if(s.charAt(j) == \'a\'){\n                j--; \n                i++;\n            }else{\n                arr[i] = \'a\';\n                return new String(arr);\n            }\n        }\n        arr[s.length() - 1] = \'b\';\n        return new String(arr);\n    }\n}\n```
