Dado un número n, compruebe si el K-ésimo bit de n está activado o no.
Ejemplos:
C++
// CPP program to check if k-th bit
// of a given number is set or not
#include <iostream>
using namespace std;
void isKthBitSet(int n, int k)
{
if (n & (1 << (k - 1)))
cout << "SET";
else
cout << "NOT SET";
}
// Driver code
int main()
{
int n = 5, k = 1;
isKthBitSet(n, k);
return 0;
}
C
// C program to check if k-th bit
// of a given number is set or not
#include <stdio.h>
void isKthBitSet(int n, int k)
{
if (n & (1 << (k - 1)))
printf("SET");
else
printf("NOT SET");
}
// Driver code
int main()
{
int n = 5, k = 1;
isKthBitSet(n, k);
return 0;
}
// this code is contributed by devendrasaluke
Java
// Java program to check if k-th bit
// of a given number is set or not
class Number {
