Ok! here it is, the fast solution to "Number".
Bunch of if-s and all works...
long solution(long n)
{ long digits;
if(n<10)
digits=n;
else if(n<100)
digits=(n-9)<<1+9;
else if(n<1000)
digits=(n-99)*3+189;
else if(n<10000)
digits=(n-999)<<2+2889;
else if(n<100000)
digits=(n-9999)*5+38889;
else if(n<1000000)
digits=(n-99999)*6+488889;
else if(n<10000000)
digits=(n-999999)*7+5888889;
else if(n<100000000)
digits=(n-9999999)<<3+68888889;
else digits=788888889;
return digits;
}
It is'n very prety solution but on the other hand it is fast as lighting (:whistle: kung fu fighting).
And why can't I use tabulators! :ranting:
Any questions?
