Is 1000 a prime number? Numbers that have only 2 factors i.e. 1 and the number itself are prime numbers. Let’s find out in detail how and why is 1000 a prime number?
1.2.2 Sum of Consecutive Prime Numbers 描述:一个正整数可以表示为一个或者多个连续素数的和。比如 53 有两种表示方法 53 和 5+7+11+13+17,但是 20 的 7+13 就不能满足条件,因为7和13并不是连续的素数。 输入:输入一个正整数序列,每个数一行,在2-10000之间取值。输入结束以0表示 输出:输出的每一行对...

Help trying to find prime numbers by: Villanmac | last post by: Hi i have made the following program to make a fucntion that determines if a number is prime. Than i am supposed to use this function to print all prime numbers between 1 and 10000. What am I... C / C++ 8 ...
The output should be composed of lines each corresponding to an input line except the last zero. An output line includes the number of representations for the input integer as the sum of one or more consecutive prime numbers. No other characters should be inserted in the output. ...
10000 calls, 74626 per second. 40006 function calls in 0.138 seconds So, we can see that usingallovernot anyallows for~13651more calls per second. But, what happens when we start using larger numbers? For instance,100**10-1or99999999999999999999? You will run into an error,OverflowError: Pyt...
My latest attempt is a sieve using a Clojure hash-map, inserting all the numbers in the sieve then dissoc'ing numbers that aren't prime. At the end, it takes the key list, which are the prime numbers it found. It takes about 10-12 seconds to find 10000 prime numbers. I'm not su...

numbers here. Primes1 is faster than Primes2 as I would expect and it is clear, relatively elegant, and sufficient for me. However, I can't figure out why the ratio doesn't improve with size, and the strange results of the long typecast, and I would like to be able to understand ...
