Hello,
I have just submitted my first code and the judge rejected it because of an execution error (SIGABRT). But when I click on my orange rank, it sends me back to the page with “Accepted Test!” And the expected output is the same as my own solution. And when I compile on IDEONE, it works too.
Do you know what happened?
Here is the code in case that would be useful. The problem is CPTTRN1 - Character Patterns (Act 1)
#include <stdlib.h>
#include <stdio.h>
#define xstr(s) str(s)
#define str(s) #s
#define DIGITS 2
#define DIM_PER_CHESS 2
int * saveInput(int * t) {
if(scanf(" %"xstr(DIGITS)"d", t) == 0) return NULL;
int * allDim = (int *)calloc(*t, sizeof(int));
if(allDim == NULL) return NULL;
int i;
for(i=0; i<2*(*t); i++) {
if(scanf(" %"xstr(DIGITS)"d", allDim+i) == 0) {
free(allDim);
return NULL;
}
}
return allDim;
}
int main()
{
int t=0;
int * allDim=saveInput(&t);
if(allDim == NULL) return 1;
int chess, l, c, lines, columns;
for(chess=0; chess<t; chess++) {
lines=allDim[DIM_PER_CHESS*chess];
columns=allDim[DIM_PER_CHESS*chess+1];
for(l=0; l<lines; l++) {
for(c=0; c<columns; c++) {
if((l+c)%2 == 0) printf("*");
else printf(".");
}
printf("\n");
}
printf("\n");
}
free(allDim);
return 0;
}
