public static int[][] readBoard( Scanner sc ) Uses the provided Scanner to read the board and return a 2D integer array with the appropriate values. Input should be 9 rows of values with 9 characters each. These characters will be 1-9 to indicate a fixed number in the starting board, or a - (dash) to indicate an empty location. A value of 0 indicates an empty space in the returned array. Should return null if the board was invalid (contains invalid characters or does not contain enough values.) Example input:

In this lab, you add a loop and the statements that make up the loop body to a c++ program that is provided. when completed, the program should calculate two totals: the number of left-handed people and the number of right-handed people in your class. your loop should execute until the user enters the character x instead of l for left-handed or r for right-handed. the inputs for this program are as follows: r, r, r, l, l, l, r, l, r, r, l, x variables have been declared for you, and the input and output statements have been written.

Alook-up table used to convert pixel values to output values on a monitor. essentially, all pixels with a value of 190 or above are shown as white (i.e. 255), and all values with a value of 63 or less are shown as black (i.e. 0). in between the pixels are scaled so that a pixel with a value p is converted to a pixel of value 2/127 −+3969). if a pixel has a value of 170 originally, what value will be used to display the pixel on the monitor? if a value of 110 is used to display the pixel on the monitor, what was the original value of the pixel?
