## Hackerrank - Arrays: Left Rotation Solution

A *left rotation* operation on an array shifts each of the array's elements unit to the left. For example, if left rotations are performed on array , then the array would become .

Given an array of integers and a number, , perform left rotations on the array. Return the updated array to be printed as a single line of space-separated integers.

**Function Description**

Complete the function *rotLeft* in the editor below. It should return the resulting array of integers.

rotLeft has the following parameter(s):

- An array of integers .
- An integer , the number of rotations.

**Input Format**

The first line contains two space-separated integers and , the size of and the number of left rotations you must perform.

The second line contains space-separated integers .

**Constraints**

**Output Format**

Print a single line of space-separated integers denoting the final state of the array after performing left rotations.

**Sample Input**

```
5 4
1 2 3 4 5
```

**Sample Output**

```
5 1 2 3 4
```

**Explanation**

When we perform left rotations, the array undergoes the following sequence of changes:

### Solution in Python

```
def rotLeft(a, d):
d = d%len(a)
a = a[d:]+a[:d]
return a
n,d = map(int,input().split())
a = list(map(int,input().split()))
print(*rotLeft(a, d))
```
