how to remove the runtime (NZEC) error in my python code? -

-

i trying solve prime generator problem prime1 in spoj.com getting runtime error(nzec). problem needs take number of test cases , each test case, needs input 2 numbers in line each different test case , print output prime numbers in range of each number error runtime error time: 0.01 memory: 7736 signal:-1

    # code goes here  def is_prime(x):     if x<2:         return false     if x==2:         return true     y in range(2,x):         if x%y==0:             return false     return true t=int(raw_input()) mylist=[]  in range(0,t):     a=raw_input()     a=a.split(' ')     mylist.append(int(a[0]))     mylist.append(int(a[1])) k=0 while k<len(mylist):     c=mylist[k]     k+=1     d=mylist[k]     k+=1     z in range(c,d+1):         if is_prime(z):             print z     print

your issue raw_input() returns string , not integer. trying use directly in range() function - for in range(0,t) . range() function accepts integers arguments, need convert input int before using in range.

t=int(raw_input())

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl

python - PyCharm Type error Message -

i'm newbie trying out ml/dbn in python (3.4) under pycharm (comm.ed 4.5). following definition def make_thetas(xmin,xmax,n): xs = np.linespace(xmin,xmax,n) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1] + widths return thetas throws error "class 'tuple' not define ' sub ', '-' operator cannot used on instance" on - operator on third line (widths = ....) ideas on how code running under pycharm - works alright in interactive python window. thx. to all, after g'g lot have found workaround seems work within pycharm. workaround because (even python newbie) expected python not need explicit typecasting, not when using datatypes imported lib such numpy. def make_thetas(xmin,xmax,n): xs = np.array(np.linspace(xmin,xmax,n)) widths = (xs[1:] - xs[:-1])/2.0 thetas = xs[:-1]+ widths return thetas using docstrings type-hinting such below did not work def make_thetas(xmin,xmax,n): "&q
