LeetCode 1754: Largest Merge Of Two Strings
LeetCode 1754 Solution Explanation
Explanation:
To solve this problem, we can use a greedy approach. We compare the current characters of word1 and word2, and choose the larger character to append to the merge string. If the characters are equal, we compare the following characters until we find a difference.
We iterate through the strings until one of them becomes empty, and then append the remaining characters of the non-empty string to the merge string.
Solution:

class Solution {
public String largestMerge(String word1, String word2) {
StringBuilder merge = new StringBuilder();
while (!word1.isEmpty() && !word2.isEmpty()) {
if (word1.compareTo(word2) > 0) {
merge.append(word1.charAt(0));
word1 = word1.substring(1);
} else {
merge.append(word2.charAt(0));
word2 = word2.substring(1);
}
}
merge.append(word1).append(word2);
return merge.toString();
}
