第二步,判断第一步获取的1的个数是否是一个素数,通过一个辅助方法来实现,如果是素数,计数count加1。 publicintcountPrimeSetBits(intL,intR){intcount=0;for(inti=L; i<=R; i++) {intcnt=Integer.bitCount(i);if(isPrime(cnt)) { count++; } }returncount; }/** * 素数:只能被1和自身整除。 *@...
762. Prime Number of Set Bits in Binary Representation # 题目 # Given two integers L and R, find the count of numbers in the range [L, R] (inclusive) having a prime number of set bits in their binary representation. (Recall that the number of set bits
Given two integersLandR, find the count of numbers in the range[L, R](inclusive) having a prime number of set bits in their binary representation. (Recall that the number of set bits an integer has is the number of1s present when written in binary. For example,21written in binary is101...

Write a function that takes an unsigned integer and returns the number of ’1' bits it has (also known as the Hamming weight). For example, the 32-bit integer ’11' has binary representation 00000000000000000000000000001011, so the function should return 3. 解题思路: 此题为计算海明距离。先将...
1.1 Binary Theory 1.1.1 Introduction Binary is a base-2 number system that uses two mutually exclusive states to represent information. A binary number is made up of elements called bits where each bit can be in one of the two possible states. Generally, we represent them with the numerals...
Given a positive integer, check whether it has alternating bits: namely, if two adjacent bits will always have different values. Example 1: Input: 5 Output: True Explanation: The binary representation of 5 is: 101 1. 2. 3. 4. Example 2: ...
