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...

Let’s start with a isPrime function. To determine if a number is prime, we need to check if it is not divisible by any number less than n. The runtime complexity of isPrime function would be O(n) and hence counting the total prime numbers up to n would be O(n2). Could we do ...
The standard approach to solving this problem is to first take input in the code itself. The input for our given problem is an integer number. To find log in java, to make things simpler, the Math package in Java already has a built in method named log for this. ...
