計算量

$O(1)$

使い方

そのままなので省略

Verified with

• グラフ - WarshallFroydのテスト (tests/graph.shortest_path.warshall_froyd.test.cpp)
• 型変換のテスト (tests/various.convert.test.cpp)

Code

#pragma once
char int_to_char(int x) { return (char)(x + '0'); }
char int_to_alph(int x) { return (char)(x + 'a'); }
int char_to_int(char c) { return (int)(c - '0'); }
string int_to_string(long long x) { return to_string(x); }
long long string_to_int(const string &s) { return stoll(s); }
