# Find the “Kth” max and min element of an array ## “Kth” max and min element in Python

In this article we will see a python program to find kth max and min element of an array. User will enter array and value of k. And then compiler will give output of k th smallest and k th largest element.

Let’s consider an example:

• array=  [1, 7, 6, 8, 9, 2, 4, 5, 3, 0] k = 2
• kth largest element: 8
• kth smallest element: 1

### Algorithm

• Step 1: Call findkmax and findkmin and pass array and value of k.

#### Algorithm for Function findkmax

• Step 1: Sort the array in descending order using predefined function sort
• Step 2: print array[k-1] after sorting the array in descending order

#### Algorithm for Function findkmin

• Step 1: Sort the array in ascending order using predefined function sort
• Step 2: print array[k-1] after sorting the array in ascending order ### Python code

Run
```def findkmax(k, array):
# sort the array in descending order
array.sort(reverse=True)

# Since indexing start from 0, hence if user want first number, that means index=0
print("K th maximum element is: ", array[k - 1])

def findkmin(k, array):
# sort the array in ascending order
array.sort()

# Since indexing start from 0, hence if user want first number, that means index=0
print("K th minimum element is: ", array[k - 1])

array = [1, 7, 6, 8, 9, 2, 4, 5, 3, 0]
k = 2

# call function findkmax
findkmax(k, array)

# call function findkmin
findkmin(k, array)
```

### Output

```K th maximum element is: 8
K th minimum element is: 1```

### Optimal solution (Python Code)

Run
```def find(k, arr, l):
# sort the array in descending order
arr.sort(reverse=True)

# Since indexing start from 0, hence if user want first number, that means index=0
print("K th maximum element is: ", arr[k - 1])

# Since the array is sort in reverse order for minimum we have to find from end
print("K th minimum element is: ", array[l - k])

array = [1, 7, 6, 8, 9, 2, 4, 5, 3, 0]
k = 2
# call function
find(k, array, len(array))
```

### Output

```K th maximum element is: 8
K th minimum element is: 1```
