# Intuition\n<!-- Describe your first thoughts on how to solve this problem. -->\n\nRemoved the use of StringBuilder s1, as it was not necessary for the task. Instead, I directly manipulated the char array ch.\nRemoved the unnecessary sorting of s1, as you only need to replace characters with the smaller of the two.\nUsed (char) Math.min(ch[i], ch[j]) to determine the smaller character between ch[i] and ch[j].\nChanged the loop condition to i < j to properly compare and replace characters.\nThis corrected code should now correctly modify the given string s to create the smallest palindrome possible by replacing characters.\n\n# Complexity\n- Time complexity:\n<!-- Add your time complexity here, e.g. $$O(n)$$ -->\n\n- Space complexity:\n<!-- Add your space complexity here, e.g. $$O(n)$$ -->\n\n# Code\n```\nclass Solution {\n    public String makeSmallestPalindrome(String s) {\n        char[] ch = s.toCharArray();\n\n        for (int i = 0, j = ch.length - 1; i < j; i++, j--) {\n            if (ch[i] != ch[j]) {\n                char smallerChar = (char) Math.min(ch[i], ch[j]);\n                ch[i] = smallerChar;\n                ch[j] = smallerChar;\n            }\n        }\n\n        return new String(ch);\n    }\n}\n\n```
