odd numbers 1 to 1000

Today, we see a mention of this in the tech group: the sum of numbers that are divisible by 3 or 5 within 1000. It is interesting to see the solution two, the beginning is quite confused, and then thought, and then by people pointing, feel the Enlightenment. The first solution is very common, that is, 1000 of the number are traversed once, as long as there is

Problem Description: Enter an array of integers to implement a function to adjust the order of numbers in the array, Yes, all the odd digits are in the first half of the array, and all the even digits are in the second half. Thinking Analysis: Use two pointers, one to the array header, one to the end of the array, one to the other, the other for the even number in front, One in the back to find the

From the surface looks like this topic is very simple, actually does not have the imagination simple, the individual thought the more difficult point is that when the odd even number has been separated but the order is not arranged, the operation of the two-part array is somewhat complicated.
