Explanation: Diagonal index are same for rows and columns so we need to assign 1.
For the values above diagonal row# > col#.
For the values below diagonal row# < col#.
CODE (Python):
def set2DArray(N):
arr = []
for i in range(0, N):
arr.append([])
for j in range(0, N):
arr[i].append(0)
if i == j:
arr[i][j] = 1
elif i < j:
arr[i][j] = i + j
else:
arr[i][j] = i - j
return arr
N = int(input("Enter N: "))
arr = set2DArray(N)
print(arr)

Submit Chapter7.java with four (4) public static methods as follows: A. Write a method called mostCommon that accepts an array of integers as its only parameter, and returns the int that occurs most frequently. Break ties by returning the lower value For example, {1,2,2,3,4,4} would return 2 as the most common int. B. Write mostCommon (same as above) that accepts an array of doubles, and returns the double that occurs most frequently. Consider any double values that are within 0.1%...

Define a two-dimensional int array which has 5 rows and 3 columns. The elements in array is randomly initialized (using Math.random()). Write a method to find the maximum value in this two dimensional array; Write a method to find the average value in the array; Write a method to count how many elements are smaller than average; Write a method to copy contents in a two-dimensional array to a one-dimensional array. The method will return this one-dimensional array. Method is...

IN C++ Please!! Declare a global integer constant called SIZE and initialize it to 10. • Declare a global enum variable that will support 10 values – each representing an ant colony {A, B, C, D, E, F, G, H, I, J}. • In the main function, o Declare a 2-dimensional array of size the global integer constant, SIZE. The number of rows and columns should be equal to SIZE, which would make this a square matrix. This array will...

I'm a little crunched for time and need some help with these first two questions. Thank you! Question 1.) Write a Java program that reads in sequence of integers from the user until user enters a negative number and stores them in an Integer ArrayList. Once read, display a bar chart based on the values stored in the ArrayList. For example, if the user inputs 2, 5, 3, 8, 4, and -1, then your program should display the bar chart...
