要檢查回文數，假設我們的數字是5，其二進位為−
101
The palindrome of 101 is 101 and to check you need to reverse the bits using the following function. Here, bitwise left and bitwise right shift operators are used −
public static long funcReverse(long num) {
long myRev = 0;
while (num > 0) {
myRev <<= 1;
if ((num & 1) == 1)
myRev ^= 1;
num >>= 1;
}
return myRev;
}然後透過從funcReverse()函數傳回和取得值，將實際表示與反向表示進行比較−
public static bool checkPalindrome(long num) {
long myRev = funcReverse(num);
return (num == myRev);
}以下是一個完整的範例，用於檢查一個數字的二進位表示是否是回文−
線上示範
using System;
public class Demo {
public static long funcReverse(long num) {
long myRev = 0;
while (num > 0) {
myRev <<= 1;
if ((num & 1) == 1)
myRev ^= 1;
num >>= 1;
}
return myRev;
}
public static bool checkPalindrome(long num) {
long myRev = funcReverse(num);
return (num == myRev);
}
public static void Main() {
// Binary value of 5 us 101
long num = 5;
if (checkPalindrome(num))
Console.WriteLine("Palindrome Number");
else
Console.WriteLine("Not a Palindrome Number");
}
}Palindrome Number
