WA 694 (The Collatz Sequence)

Can anyone help me, I got WA for this problem.

I use an unsigned long int (C++), and to limited 'a', i use this expression :

count = 0;
while (a<=l) { //a = number, l = limit
count++;
if (a==1) break;
else if (a%2) {
if (a>715827882) break;
else a=a*3+1;
}
else a/=2;
}
