# Reverse Bits LeetCode Solution

Here, We see Reverse Bits problem Solution. This Leetcode problem is done in many programming languages like C++, Java, JavaScript, Python, etc., with different approaches.

## Problem Statement ->

Reverse bits of a given 32 bits unsigned integer.

Note:

• Note that in some languages, such as Java, there is no unsigned integer type. In this case, both input and output will be given as a signed integer type. They should not affect your implementation, as the integer’s internal binary representation is the same, whether it is signed or unsigned.
• In Java, the compiler represents the signed integers using 2’s complement notation. Therefore, in Example 2 above, the input represents the signed integer `-3` and the output represents the signed integer `-1073741825`.
```Example 1:
Input: n = 00000010100101000001111010011100
Output:    964176192 (00111001011110000010100101000000)
Explanation: The input binary string 00000010100101000001111010011100 represents the unsigned integer 43261596, so return 964176192 which its binary representation is 00111001011110000010100101000000.

Example 2:
Input: n = 11111111111111111111111111111101
Output:   3221225471 (10111111111111111111111111111111)
Explanation: The input binary string 11111111111111111111111111111101 represents the unsigned integer 4294967293, so return 3221225471 which its binary representation is 10111111111111111111111111111111.
```

## Reverse Bits Leetcode Solution C++ ->

``````class Solution {
public:
uint32_t reverseBits(uint32_t n) {
uint32_t res = 0;
for (int i = 0; i < 31; i++) {
res = (n % 2) + res << 1;
n >>= 1;
}
return res + n % 2;
}
};
```Code language: C++ (cpp)```

## Reverse Bits Leetcode Solution Java ->

``````public class Solution {
public int reverseBits(int n) {
int res=0;
for(int i=0;i<32;i++){
res= ( res << 1 ) | ( n & 1 );
n = n >> 1;
}
return res;
}
}
```Code language: Java (java)```

## Reverse Bits Leetcode Solution JavaScript ->

``````var reverseBits = function(n) {
};
```Code language: JavaScript (javascript)```

## Reverse Bits Leetcode Solution Python ->

``````class Solution:
def reverseBits(self, n):
oribin='{0:032b}'.format(n)
reversebin=oribin[::-1]
return int(reversebin,2)
```Code language: Python (python)```
