My code is running fine on my computer but during my attempts to upload it to leet code it shows the following:
Line 20: Char 18: runtime error: index 10 out of bounds for type 'int [10]' [solution.c]
int romanToInt(char * s){
char a[7]={'M','D','C','L','X','V','I'};
int b[7]={1000,500,100,50,10,5,1};
int x;
x=strlen(s);
int c[x];
for(int i=0;i<x;++i)
{
for(int j=0;j<7;++j)
{
if(s[i]==a[j])
{
c[i]=b[j];
break;
}
}
}
int sum=0;
for(int i=0;i<x;++i)
{
if(c[i]<c[i+1]&&i!=x-1)
{
sum-=c[i];
}
else
{
sum+=c[i];
}
}
//printf("%d",sum);
return sum;
}
Running the same code on my computer using it as a custom function works just fine
#include <stdio.h>
#include<string.h>
int romanToInt(char * s);
void main()
{
char a[100];
char* p;
gets(a);
p=a;
int sum= romanToInt(p);
printf("%d",sum);
}
int romanToInt(char * s){
char a[7]={'M','D','C','L','X','V','I'};
int b[7]={1000,500,100,50,10,5,1};
int x;
x=strlen(s);
int c[x];
for(int i=0;i<x;++i)
{
for(int j=0;j<7;++j)
{
if(s[i]==a[j])
{
c[i]=b[j];
break;
}
}
}
int sum=0;
for(int i=0;i<x;++i)
{
if(c[i]<c[i+1]&&i!=x-1)
{
sum-=c[i];
}
else
{
sum+=c[i];
}
}
//printf("%d",sum);
return sum;
}
Why isn't leet code accepting this result?
