和第二种解法的思路类似,将20个数变成布尔类型的数组,计算出二进制数中1的个数当做数组的下标去匹配。 publicintcountPrimeSetBits3(intL,intR){intcount=0;boolean[] arr = {false,false,true,true,false,true,false,true,false,false,false,true,false,true,false,false,false,true,false,true};for(inti=L...
A random number is a number generated in such a way that each possible value has an equal chance of being selected. In computing, random numbers are often used for tasks such as creating unique identifiers, randomizing game elements, or simulating randomness in algorithms. 1. Using the java....
int n; n=Convert.ToInt32(Console.ReadLine()); bool prime = true; for(int i=2;i<n/2;i++) { if(n%i==0) { prime=false; break; } } if(prime==true) { Console.WriteLine("{0} is prime.",n); } else { Console.WriteLine("Not prime!"); } c#optimizationprimenumberalgorythm...
Instead of giving input in the code, using Scanner class in Java, we can read input at runtime itself. So, making use of this for our problem, we read the inputs – number whose log has to be found (n) and the base for log (b). As log is not fixed,it could be anything othe...
Hi there! just for the fun of it ,write a code to print out the list of all prime numbers less than a certain value! Lets see who will go highest!! Happy Coding https://code.sololearn.com/cHgt6aag99I8/?ref=app htmljavascriptc++javacrubypython3prime_numbers ...

If you want to square a number in Java, just multiply it by itself. So for example ? 1 } while ((indexMark ^ 2) <= primes.get(primes.size() -1)); could be replaced with ? 1 } while ((indexMark * indexMark) <= primes.get(primes.size() -1)); I make no comment on ...
