/*var arr = readline().split(" ") var n = arr[0]; var q = arr[1]; var target = readline().split(" ") var o = [] for(let i = 0;i<q;i++) o.push(parseInt(readline()));*/ let target = [1,2,3] const q = 2; const o = [3,3] for(let i = 0;i<q;i++){ let count = 0; target = target.map(item => { if(item>=o[i]){ count++; return --item; } else return item; }) console.log(count); } 这个第四题的0%，有人帮我看看原因吗
