可以使用BigInteger。通过new BigInteger(String.valueOf(value))来处理超出long范围的值。
import java.math.BigInteger; class Solution { public String addBinary(String a, String b) { // BigInteger x = new BigInteger(a, 2), y = new BigInteger(b, 2); // return x.add(y).toString(2); StringBuffer ans = new StringBuffer(); int m = a.length(), n = b.length(), k ...
. BigInteger provides analogues to all of Java's primitive integer operators, and all relevant methods from java.lang.Math. Additionally, BigInteger provides operations for modular arithmetic, GCD calculation, primality testing, prime generation, bit manipulation, and a few other miscellaneous operations...
Bit operations operate on a single bit of the two's-complement representation of their operand. If necessary, the operand is sign-extended so that it contains the designated bit. None of the single-bit operations can produce a BigInteger with a different sign from the BigInteger being operated...
Input a number: 127 127 is a Mersenne number. Flowchart: For more Practice: Solve these Related Problems: Write a Java program to check if a number is a Mersenne number by verifying if it can be written as 2^n - 1 using bitwise operations. ...
You can think of them as an intelligent blend of fixed-precision native integers—or primitive integer types, as Java calls them—and Java’s BigInteger numbers, with the following consequences:You have all the conveniences of arbitrary-precision integers, and you can use all the well-known ...

The BigInteger class also support bitwise operations (see e129 对Big Integer进行位操作). However, a BigInteger object is immutable where a BitSet is mutable. // Create the bitset BitSet bits = new BitSet(); // Set a bit on bits.set(2); // 100 = decimal 4 // Retrieving the value of...
An arbitrary-precision integer replacement for java.math.BigInteger, with the following differences: Mutable: BigInt is mutable, allowing for reuse of allocated magnitude arrays. Little-endian: BigInt's magnitude array is in little-endian order, allowing for faster operations concerning changes to a...
BigInteger - Class in java.math Immutable arbitrary-precision integers. BigInteger(byte[]) - Constructor for class java.math.BigInteger Translates a byte array containing the two's-complement binary representation of a BigInteger into a BigInteger. BigInteger(byte[], int, int) - Constructor for cla...
