For this exercise, use the following 2D array, which is already declared and initialized in your programming environment below. Do not rename the provided array - your program should refer to it as a. 34 38 50 44 39 42 36 40 43 44 24 31 46 40 45 43 47 35 31 26 37 28 20 36 50 Your task is to output the sum of all values in the 2D array, along with the average of all values in the 2D array, as seen in the sample run below. Note: Be sure that your program accounts for arrays of any size, not just arrays that are 5 x 5. Your program will be tested against arrays of size n by n. It should work for any square array, not just the one shown. You should also use for loops in your program, not while loops. Sample Run Sum of all values: 949 Average of all values: 37.96
