Write the method lightenImage that modifies the image by changing the values in the instance variable pixels according to the following conditions:

The value at position $($row$,$ col$)$ is increased by the value at $($row $+2,$ col $+2),$ if the position is valid.

If the new value is greater than the value WHITE, the pixel is assigned the value WHITE.

If there is no pixel at position $($row $+2,$ col $+2),$ the value is unchanged.

The following shows the contents of the instance variable pixels before and after a call to lightenImage. The bolded values represent the values that could be modified in the image.

Complete the method lightenImage below.

$/*$ Increases the value of each pixel at $($row$,$ col$)$

$*$ by the value of the pixel at $($row $+2,$ col $+2)$ if

$*$ the position is valid. If the value is greater

$*$ than WHITE, the pixel value is set to WHITE.

$*$ If there is no pixel at $($row $+2,$ col $+2),$ the

$*$ value is unchanged.

$*/$

public void lightenImage$()$ The method must do the following: Accesses all necessary elements in at least one row or one column of pixels

Accesses all necessary elements of pixels $($no bounds errors$)$

Increases the value at index $[$row$][$col$]$ by the value found at index $[$row$+2][$col$+2]$

Modifies all appropriate elements of pixels

Assigns WHITE or $255$ to elements of pixels that would otherwise have a value greater than WHITE
