D-Programming-Practice

This repository provides two experimental tools (judge.d, gen.d) for atcoder contest.

  • gen.d: generate test headers from the contest name (e.g., ./gen.d abc089)
  • judge.d: test input/output strings in a header of a source code (e.g., ./judge.d ./atcoder/abc089/A.d

usage of ./gen.d

For example, ./gen.d abc089 generates template codes with test header A.d, B.d, C.d, D.d in atcoder/abc089 by parsing atcoder task pages.

usage of ./judge.d

there are three supported test formats. here I introduce the easiest one.

An input file ./atcoder/abc081/b.d contains inline test cases

import std.array;

int count2(int x) {
    int ret = 0;
    while (x % 2 == 0) {
        ++ret;
        x /= 2;
    }
    return ret;
}

void main() {
    size_t n;
    string s;
    readf("%d\n%s\n", &n, &s);
    auto c = s.split().map!(a => a.to!int.count2).reduce!min;
    writeln(c);
}

then $ ./judge.d ./atcoder/abc081/b.d results

$ ./judge.d atcoder/abc081/b.d
