HackerRank Project Euler #1
<p>What is wrong with this code? It is not passing case 2 &amp; 3 on HackerRank.</p>

<pre><code>T=long(input())
while T&gt;0:
    N=long(input())
    sum=0
    for i in range (1,N):
        if i%3==0 or i%5==0:
            sum+=i
    print (sum)
    T-=1
</code></pre>

<p>I'm new in programming and can't figure out what I did wrong.</p>
