#include "src/base/macro.hpp"
コンテスト用のマクロです。型の別名 と、入力用のマクロが使う 入出力 を include し、最適化の #pragma (avx2、O3、unroll-loops) も設定します。
void solve() {
LL(n, m); // long long n, m; を読む
VL(a, n); // vector<long long> a(n); を読む
rep(i, n) a[i] += m;
std::sort(all(a));
if (a[0] > 0) { Yes } // "Yes" を出力して return
No
}
ループ
ループ変数はすべて long long です。
| マクロ | 意味 |
|---|---|
rep(n) |
n 回繰り返す |
rep(i, n) |
i = 0, 1, ..., n-1 |
rep(i, a, n) |
i = a, a+1, ..., n-1 |
rep(i, a, n, t) |
i = a, a+t, ... (n 未満) |
repd(i, n) |
i = n-1, n-2, ..., 0 |
repd(i, a, n) |
i = n-1, n-2, ..., a |
repd(i, a, n, t) |
i = n-1, n-1-t, ... (a 以上) |
rrep(i, n) |
i = 1, 2, ..., n |
rrepd(i, n) |
i = n, n-1, ..., 1 |
all(v) |
v.begin(), v.end() |
入力
宣言と読み込みを同時に行います。
| マクロ | 宣言される変数 |
|---|---|
LL(a, b, ...) |
ll a, b, ...; |
STR(s, t, ...) |
str s, t, ...; |
IN(T, x) |
T x; |
CHAR(c) |
char c; |
VL(a, n) / VC(a, n) / VS(a, n) / VPL(a, n)
|
長さ n の vl / vc / vs / vpl
|
VVL(a, n, m) |
n × m の vvl
|
AL(a, k) / AAL(a, n, m)
|
al<k> / aal<n, m>
|
VAL(a, n, k) |
長さ n の val<k>
|
SL(a, n) |
n 個読んだ sl (set<ll>) |
scan(a, b, ...) で、宣言済みの変数を読むこともできます。
出力して終了
文字列を出力して改行し、return; します。戻り値が void の関数 (solve など) の中で使います。
| マクロ | 出力 |
|---|---|
Yes / No
|
Yes / No
|
YES / NO
|
YES / NO
|
Takahashi / Aoki
|
Takahashi / Aoki
|
