--DAY 4--
Hi, I am going to make #100DaysOfCode Challenge.Everyday I will try solve 1 problem from leetcode or hackerrank. Hope you can go with me until end.
Now let's solve problem today:
-Problem: Longest Common Prefix
-Detail: https://leetcode.com/problems/longest-common-prefix/
-My solution (javascript):
var longestCommonPrefix = function(str) {
if(str.length==0) return '';
let prefix='';
for(let i=0;i<str[0].length;i++){
let check=true;
for(let j=1;j<str.length;j++){
if(str[j].charAt(i)!=str[0].charAt(i)){
return prefix;
}
}
if(check) prefix+=str[0].charAt(i);
}
return prefix;
};
