Bitwise operators (`&`, `|`, `^`, `<<`, `>>`) have identical syntax in all three. Two patterns you will use constantly in DSA:

**C++ and Java**
**C++**
```cpp
if (x & 1) // true if x is odd - faster than x % 2 == 1
if (x & 1) // true if x is odd (any non-zero integer treated as true) - faster than x % 2 == 1
x = x << 1; // multiply by 2
x = x >> 1; // integer divide by 2
```

**Java**
```java
if((x & 1) != 0 ) // true if x is odd (no implicit conversion from int to boolean unlike c++)
x = x << 1; // multiply by 2
x = x >> 1; // integer divide by 2
```
