#pragma comment(linker, "/STACK:16777216")
#include <stdio.h>

char str[size];
char arr[size];
int i=0;
 void recurse(int low,int high){
      int mid;
     if(low>high)
         return;
     mid = (low+high)/2;
     arr[mid] = str[i++];
     recurse(low,mid-1);
     recurse(mid+1,high);
 }

 int main(){
    scanf(" %[^\n]s",str);
    recurse(0,strlen(str)-1);
    printf("%s\n",arr);
 return 0;
 }

/*I simply used recursion and its working for all the test I know presently.Please tell me what is the problem in the code*/

the same

def solve(str):
    l = len(str)
    if l<=2:
        return str
    mid = (1+l)//2
    return solve(str[1:mid]) + str[0] + solve(str[mid:])

print solve(sys.stdin.readline().strip())

it's working for all the test I know, but get WA3 here

Xel,отличное решение!
Только вместо функции strip() нужна функция strip('\n'),
иначе удаляются все концевые пробелы и этим самым
нарушаются входные данные.
