今日の問題

↑押してください。

自分の回答(javascript)

function Main(input){
    min = 1e18
    max = -1e18
    let abc = "abcdefghijklmnopqrstuvwxyz".split("")
    let ABC = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".split("")
    let f = 3
    if(f == 0){
      input = parseInt(input.trim())
    }
    if(f == 1){
      input = input.trim().split("\n").map((a)=>parseInt(a))
    }
    if(f == 2){
      input = input.trim().split("\n").map((a)=>a.split(" ").map((b)=>parseInt(b)))
    }
    //ここより上は定型文です。
   input = input.trim().split("\n")
   let [n,k] = input.shift().split(" ").map((a)=>parseInt(a))
   let s = input.shift().split("")
   j = n-1
   for(let i = 0;i<k;i++){
     while(s[j] == "."){
       j --
     }
     s[j] = "."
   }
   console.log(s.join(""))
   }
  Main(require("fs").readFileSync(0, "utf8"));
  

工夫した点

右から順に見ていきます。wlile文で途中にある"."を飛ばします。"@"だったら"."にして次に進みます。
