Explanation: The length of longest continuous increasing subsequence is 1, and there are 5 subsequences' length is 1, so output 5. 1. 2. 3. Note: Length of the given array will be not exceed 2000 and the answer is guaranteed to be fit in 32-bit signed int. ...
Write a function that takes an unsigned integer and returns the number of ’1' bits it has (also known as theHamming weight). For example, the 32-bit integer ’11' has binary representation00000000000000000000000000001011, so the function should return 3. ...
