Hi, I am trying to solve 118A - Упражнение на строки and the output I have in my pc is different than the output in codeforces. My submission:26568938 My code: ~~~~~

include <stdlib.h>

include <stdio.h>

include <ctype.h>

include <string.h>

include <stdio.h>

int main() { char str1[101],str2[202]; gets(str1); int i,j=1; for(i=0;i<strlen(str1);i++) { str1[i]=tolower(str1[i]); switch (str1[i]) { case 'a': case 'o': case 'e': case 'y': case 'i': case 'u': continue; default : { str2[j]=str1[i]; j=j+2; }

}
}
for(j=0;j<strlen(str1)*2;j=j+2)
    str2[j]='.';
if(isalpha(str2[strlen(str2)-1]))
    str2[strlen(str2)]='\0';
else
    str2[strlen(str2)-1]='\0';
printf("%s\n",str2);

return 0;

}
