Solution in Python (3.4.3) (judge verdict: Runtime Error)

K,S=map(int,input().split())
sum=0
count=0
for i in range(K+1):
    sum+=i
    a=sum
    L=S-sum
    #print(L)
    LL=min(L,K)
    for j in range(LL+1):
        sum+=j
        if S-sum>=0 and S-sum<=K :
            count+=1
            #print(str(i)+" "+str(j))
        sum=a #jを足す前に戻す
    sum=0
print(count)
