My solution to the problem PRPALIN. I have spent a lot of time trying to debug this program but for higher numbers I am getting the SIGSEV signal. When I try to run it on local machine for higher values its returning me a segementation fault. I have tried many things some really stupid things like < to <= or similar things but I can’t reach to the answer.
One more problem that I am facing is that in the function void palindrome(long long int a) why the assignment of rev doesn’t take place on array_pp.
while(x<1000000)
{
long long int rev=0;
long long int p = x;
while(p>0)
{
rev=rev*10+p%10;
p=p/10;
}
if(x==rev)
if(rev%2!=0)
{
array_pp[k]=rev;
k++;
printf("%lld",array_pp[k]);//however ,"%lld",rev gives the desired result
}
x++;
}
Either both the problems are interconnected or there’s something about static variables that I am missing.
Algorithm
I compute all the Palindromes starting from the input a. Then calculate those values which are palindromes and prime and then compute the result.
When I am running the program with the palindrome list starting from the number ‘1’ I am getting a TLE with runtime 1.01 sec and when I pass the input as an argument the code fails.
Please help. Also , I need some help as to how can I make my code more bug free because in competitions I wont have this liberty to ask doubts.
Thankyou
