+## Ones and Zeros
+
+Given an array of ones and zeroes, convert the equivalent binary value to an integer.
+
+>Eg: `[0, 0, 0, 1]` is treated as `0001` which is the binary representation of `1`.
+
+**Examples:**
+
+```rust
+Testing: [0, 0, 0, 1] ==> 1
+Testing: [0, 0, 1, 0] ==> 2
+Testing: [0, 1, 0, 1] ==> 5
+Testing: [1, 0, 0, 1] ==> 9
+Testing: [0, 0, 1, 0] ==> 2
+Testing: [0, 1, 1, 0] ==> 6
+Testing: [1, 1, 1, 1] ==> 15
+Testing: [1, 0, 1, 1] ==> 11
+```
+
+>*However, the arrays can have varying lengths, not just limited to 4.*
