겹치는 가장 긴 prefix를 구하는 문제이다. 단순하게 풀었다. 이 문제도 C#

// C#
public class Solution {
    public string LongestCommonPrefix(string[] strs) {
        if(strs.Length<1)
            return "";
        string result="";
        string source=strs[0];
        for(int i=0;i<source.Length;i++) {
            char cmpChar = source[i];
            for(int j=1;j<strs.Length;j++) {
                if(i>=strs[j].Length)
                    return result;
                if(strs[j][i]!=cmpChar)
                    return result;
            }
            result+=cmpChar;
        }
        return result;
    }
}
