Author Question: **Giappi**
I have an integer number, which I want to reverse by following steps:
1. Convert the number into binary string.
2. Reverse binary string.
3. Convert the reversed binary string back to integer.
Can you help me write a function to do it ?
**Example**
For `x = 234`, the output should be `ReverseBit(x) = 87`.
`23410 = 111010102 => 010101112 = 8710`.
**Input/Output**
* **[input] integer x**
A non-negative integer.
* **[output] integer**
x reversed as described above.
**Solution:**
```python
def ReverseBit(x):
x = bin(x).replace('0b', '')
reverse_text = ''
for l in range(len(x)-1, -1, -1):
reverse_text = reverse_text + x[l]
return int(reverse_text, 2)
>>> ReverseBit(234)
87
>>>
```
