+# [Arrays: New Year Chaos](https://www.hackerrank.com/challenges/minimum-swaps-2)
+
+Return the minimum number of swaps to sort the given array.
+
+- Difficulty:  ` #medium `
+- Category: ` #ProblemSolvingIntermediate `
+
+You are given an unordered array consisting of consecutive integers
+[1, 2, 3, ..., n] without any duplicates. You are allowed to swap any
+two elements. Find the minimum number of swaps required to sort the
+array in ascending order.
+
+## Example
+
+` arr = [7, 1, 3, 2, 4, 5, 6] `
+
+Perform the following steps:
+
+```text
+i   arr                     swap (indices)
+0   [7, 1, 3, 2, 4, 5, 6]   swap (0,3)
+1   [2, 1, 3, 7, 4, 5, 6]   swap (0,1)
+2   [1, 2, 3, 7, 4, 5, 6]   swap (3,4)
+3   [1, 2, 3, 4, 7, 5, 6]   swap (4,5)
+4   [1, 2, 3, 4, 5, 7, 6]   swap (5,6)
+5   [1, 2, 3, 4, 5, 6, 7]
+```
+
+It took `5` swaps to sort the array.
+
+## Function Description
+
+Complete the function minimumSwaps in the editor below.
+
+minimumSwaps has the following parameter(s):
+
+- `int arr[n]`: an unordered array of integers
+
+## Returns
+
+- `int`: the minimum number of swaps to sort the array
+
+## Input Format
+
+The first line contains an integer, , the size of .
+The second line contains  space-separated integers .
+
+## Constraints
+
+Sample Input 0
+
+- $ 1 \leq n \leq 10^5 $
+- $ 1 \leq arr[i] \leq 10^5 $
+
+## Sample Input 0
+
+```text
+4
+4 3 1 2
+```
+
+## Sample Output 0
+
+```text
+3
+```
+
+## Explanation 0
+
+Given array `arr: [4, 3, 1, 2]`
+
+After swapping `(0, 2)` we get `[1, 3, 4, 2]`
+
+After swapping `(1, 2)` we get `[1, 4, 3, 2]`
+
+After swapping `(1, 3)` we get `[1, 2, 3, 4]`
+
+So, we need a minimum of `3` swaps to sort the array in ascending order.
+
+## Sample Input 1
+
+```text
+5
+2 3 4 1 5
+```
+
+## Sample Output 1
+
+```text
+3
+```
+
+## Explanation 1
+
+Given array `arr: [1, 3, 5, 2, 4, 6, 7]`
+
+After swapping `(1, 3)` we get `[2, 3, 1, 4, 5]`
+
+After swapping `(0, 1)` we get `[3, 2, 1, 4, 5]`
+
+After swapping `(0, 2)` we get `[1, 2, 3, 4, 5]`
+
+So, we need a minimum of `3` swaps to sort the array in ascending order.
+
+## Sample Input 2
+
+```text
+7
+1 3 5 2 4 6 7
+```
+
+## Sample Output 2
+
+```text
+3
+```
+
+## Explanation 2
+
+Given array `[1, 3, 5, 2, 4, 6, 7]`
+
+After swapping `(1, 3)` we get `[1, 2, 5, 3, 4, 6, 7]`
+
+After swapping `(2, 3)` we get `[1, 2, 3, 5, 4, 6, 7]`
+
+After swapping `(3, 4)` we get `[1, 2, 3, 4, 5, 6, 7]`
+
+So, we need a minimum of `3` swaps to sort the array in ascending order.
