Write a Python code to sort a numerical array of arbitrary length $\text{'}n\text{'},$ from smallest to largest. That means after sorting, the smallest number will be the first array's element and the largest number will be the last array element. In your code design, define function for sorting and assume that the array elements are entered manually from keyboard.

To apply correction of the brightness of a Black$-$and$-$White $($BW$)$ image, we need to find the range of image intensity on pixels of an image. For simplicity, assume that the image pixel intensities have been stored in one dimensional array.

Find the minimum and the maximum pixel intensity.
