I have this code to input integer values:
```
ulong[] x;
foreach (_; 0 .. 2) { ulong a; readf!" %d"(a); x ~= a; }
end_num = max(x[0], 3);
start_num = max(x[1], 3);
if (start_num > end_num) swap(start_num, end_num);
start_num = start_num | 1; // if start_num even
add 1
end_num = (end_num - 1) | 1; // if end_num even
subtract 1
if (end_num - start_num < 2) { start_num = 7; end_num = 7; }
```
Currently I have to enter data as: 123456 789102
I'd like to enter data as: 123_456 789_10
How do I do that?
Also for output, I do this:
```
writeln("total twins = ", twinscnt, "; last twin = ", last_twin
- 1, "+/-1");
```
I'd also like to output data as: 123,987 or 123_987
About the input, see
https://issues.dlang.org/show_bug.cgi?id=20568.
A remedy is to use a `myInputText.filter!(a => a !=
'_').to!int()` etc.
```d
import std;
void main(string[] args)
{
// string[] inputs = args[1..$]; // let's not use stdin for
now
string[] inputs = ["123_456", "789_10"];
auto filtered = inputs.map!(i => i.filter!(n => n != '_'));
auto values = filtered.map!(f => f.to!int());
writeln(values.array);
}
```
About the output I see someone just post the solution ;)
