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:

  • Detail: here
  • My solution(javascript):
var maxProfit = function(prices) {
    let profit=0,buy=100000;
    for(let x of prices){
        if(x<buy) buy=x;
        if(x-buy>profit) profit=(x-buy);
    return profit;
