I have numbers from 1 to 100000. I need to remove the zeros from all numbers and sum up numbers from 1 to 100000. So if the number is 405 consider it as 45 , if number if 20039 consider it 239. My solution: for i in range(1, 100000): sum = sum + int(str(i).replace('0', '')) ...

If is a group with , whose only subgroups are and (i.e., has no proper subgroups), then , for some prime . Proof: Let with . Observe that must generate because if it didn't generate , then would be a proper nontrivial subgroup of , which would contradict our hypothesis. Hence . Thus is cyclic. ...
