Also instead of doing like

pawn Код:

new ReactionTestAlph[ ][ ] =    {
                                    "A", "B", "C" // you can add yours
                                };

We can do like

pawn Код:

new str[20],c;
for(new i=0;i<20;++i)
{
    c = random(3);
    if(c == 0) str[i] = random(10) + 48;//For numbers
    if(c == 1) str[i] = random(26) + 65;//For upper case A-Z
    if(c == 2) str[i] = random(26) + 97;//For lower case a-z
    
    c = random(2);
    if(c == 1 && i>=1)//here i>=1 means that reaction test will have min 1 digit
    {
        str[i]='\0';
        break;
    }
}
str[19] = '\0';
