Here is my problem.I think it is better than you Arsenal 13 Nov 2002 18:39

const{only 49K)
maxn=11;

var
a:array[0..maxn]of 0..9;
n,m:longint;
i,j,s:integer;
ok:boolean;

begin
fillchar(a,sizeof(a),0);
readln(n,m);
ok:=false;
if n>m then begin n:=m;ok:=true;end;
n:=n-1;
i:=maxn+1;
while n<>0 do
begin
   i:=i-1;
   a[i]:=n mod 10;
   n:=n div 10;
end;
if ok then j:=1 else j:=0;
for i:=maxn downto 1 do
begin
   s:=a[i]*2+j;
   a[i]:=s mod 10;
   j:=s div 10;
end;
i:=0;
while (a[i]=0)and(i<>maxn) do i:=i+1;
for j:=i to maxn do write(a[j]);
end.

just so so ... Coldfeel 21 Nov 2002 07:28

var m,n,y:real;b:boolean;
begin
readln(m,n);
b:=false;
if m>n then begin y:=m;m:=n;n:=y;b:=true end;
if m=0 then begin writeln(0);halt;end;
if frac(m/2)<>0 then y:=int(m/2)*4
else y:=int((m-1)/2)*4+2;
if b then writeln(y+1:0:0) else writeln(y:0:0);
end.

i think mine is better/cleaner Stefan Ciobaca 24 Nov 2002 23:25

#include <stdio.h>
#include <math.h>

int main(void)
{
    unsigned int n, m, answer;

    scanf("%u %u", &n, &m);
    if (m >= n)
        answer = 2 * (n - 1);
    else
        answer = 2 * (m - 1) + 1;
    printf("%u\n", answer);

    return 0;
}

Ok, same solution after some thinking. And it is working, just remember about huge numbers you are getting in the input

#include <iostream>
using namespace std;

int main()
{
    long long nN, nM;
    cin >> nN >> nM;
    if(nM >= nN) cout << 2*(nN-1);
    else cout << 2*(nM-1)+1;
    return 0;
}

Shortest sol (C language):

main() {
unsigned n, m;
scanf("%u%u", &n, &m);
printf("%u", n <= m ? 2 * n - 2 : 2 * m - 1);
}

#include <iostream>
using namespace std;
long long n,m;

int main()
{
    cin>>n>>m;
    if (m>=n) cout<<2*(n-1);
         else cout<<2*(m-1)+1;
}

My Solution
program Ural1224;

var
n,m:int64;

begin
readln(n,m);
if n<=m then writeln(n shl 1-2)
else writeln(m shl 1-1);
end.
