JAVA CODE PLEASE Functions with 2D Arrays Quiz by CodeChum Admin Write a program that asks the user for the row and column size of a 2D array and asks the user for the elements. Write the total of the sum of each row multiplied with the row number. Example: 1 2 3 -> (1+2+3) * 1 = 6 4 5 6 -> (4+5+6) * 2 = 30 7 8 9 -> (7+8+9) * 3 = 72 total: 108 Input 1. One line containing an integer for the number of rows 2. One line containing an integer for the number of columns 3. Multiple lines containing an integer for every element of the array for each line Output Row·size:·3 Column·size:·3 R1C1:·1 R1C2:·2 R1C3:·3 R2C1:·4 R2C2:·5 R2C3:·6 R3C1:·7 R3C2:·8 R3C3:·9 1·2·3 4·5·6 7·8·9

Circular Array 1. Palindrome Use python Write a method/function that takes in a circular array, its size and start index and finds whether the elements in the array form a palindrome or not. Return true if the elements form a palindrome, otherwise, return false. Example: Input: [20,10,0,0,0,10,20,30] (start =5, size=5) Output: True. Input:[10,20,0,0,0,10,20,30] (start =5, size=5) Output: False
