It would help if the functions had a comment explaining what
they're supposed to do, but it looks like most of them are
string functions. In D, you can concatenate strings with the
`~` operator, and utility functions like `strip` and `replace`
are in the `std.string` module:
https://dlang.org/phobos/std_string.html
I also think you defined the equivalent of these functions:
```D
import std.algorithm: swap;
import std.math: sgn, trunc;
```
As you mentioned, I retyped some of 'em:
module dcollect;
import std.stdio;
import std.conv;
/****************************************/
string strleft(const string ch, int n)
{
string ch_sub;
for(int i=0; i<n; i++)
ch_sub~=ch[i];
return ch_sub;
}
/************************************/
string strreverse(const string ch)
{
string ch_rev;
for(int i=to!int(ch.length-1); i>=0; i--)
ch_rev~=ch[i];
return ch_rev;
}
/*********************************************/
string strright(const string ch, int n)
{
string ch_sub1,
ch_sub2;
ch_sub1=strreverse(ch);
ch_sub2=strleft(ch_sub1, n);
ch_sub1=strreverse(ch_sub2);
return ch_sub1;
}
/*********************************************/
void swap(T)(ref T x,ref T y)
{
T z;
z=x;
x=y;
y=z;
}
/*********************************************/
int sgn(T)(T x)
{
if(x<0)
return -1;
else if(x>0)
return 1;
else
return 0;
}
