}The output format is incorrect.
There are three Errors in your code.
Error 1:
The common Error made by users “gets after scanf”.
Refer these links LINK1,LINK2 to know more behind it.
I had Resolved it replacing scanf with gets and then parsing the input testcase string to Integer using atoi function.
Error 2:The output format is not the same as mentioned in problem statement.
Replace “YES”,“NO”,“ERROR” by “Yes” ,“No”, “Error” as its a correct o/p format.
Error 3:You Missed the condition -“The string represents the correct pair of cells on the chess board if it composed of 5 characters” .
I have removed all three bugs that i pointed out and the following Corrected CODE WILL GET ACCEPTED .
#include<stdio.h>
#include<stdlib.h>
#include <string.h>
int main()
{
unsigned int t;
char str[15];
char kases[6];
gets(kases);
t=atoi(kases);
while(t--)
{
fflush(stdin);
gets(str);
if((strlen(str)==5) && (str[0]>='a'&&str[0]<='h')&&(str[1]>='1'&&str[1]<='8')&&(str[2]=='-')&&(str[3]>='a'&&str[3]<='h')&&(str[4]>='1'&&str[4]<='8'))
{
if((abs(str[0]-str[3])==2&&abs(str[1]-str[4])==1)||(abs(str[0]-str[3])==1&&abs(str[1]-str[4])==2))
puts("Yes");
else puts("No");
}
else
puts("Error");
}
return 0;
}
thanxx…
