Ecc/EDC Algorithm

Theory: 4-byte error code EDC: In the CD-ROM sector, there is a 4-byte 32-bit EDC domain, which is used to store the CRC code. The CRC verification code of the CD-ROM generates a polynomial of 32th order, p (x) = (x16 + x15 + X2 + 1) (x16 + X2 + x + 1 ). The data block used to calculate the CRC code is the Data byte from the beginning of the slice to the end of t

Java algorithms: 1. skip steps; 2. Calculate the number of 1 in binary; 3. Calculate the number of 1 in decimal.

Some small algorithms are of the Java version, and a large number of questions on the network are aimed at C ++. Therefore, Java implementation is rare, but they are the basis of the test, The implementation is the same. You can broaden your thinking and be helpful. /*** 1 hop steps* Question: there are N levels in a step. If you can skip 1 level at a time, you can also skip 2 levels.* Calculate the total number of hops in total and analyze the time
