In an array, contiguous memory spaces are often used to store actual values, but not in an ArrayList.
Explain.
The array index can be any integer less than the array size… TRUE OR FALSE

- Assignment Write a program that reads a 2D array of chars, checks, and corrects each char within this array, and print out the corrected 2D array. First the program will read the row count (rowCount) and column count (columnCount) of the 2D array, both as int values. Then, the chars constituting the 2D array will be read on a row-by-row basis. After reading the 2D array, the program will check and correct each char within the 2D array according to the rules below. This process MUST be done by using a void function by sending the appropriate cell of the 2D array with a call-by-reference fashion. • If the row index is an even number, a char can only be a lowercase English value. • If the row index is an odd number, a char can only be ?, 7', or X'. • Any incorrect value MUST be changed into Finally, the checked and corrected 2D array will be printed out to the screen.

A selection sort compares every element of an array with all the other elements of the array and exchanges their values if they are out of order. After the first pass of a selection sort, the first array element is in the correct position; after the second pass the first two elements of the array are in the correct position, and so on. Thus, after each pass of a selection sort, the unsorted portion of the array contains one less element. Write and test a function that implements this sorting method.arrow_forwardIn the square two dimensional array, the condition to navigate to (reach) the upper triangle elements of the primary diagonal * :is Note: (i) represents row index, (j) represents column index, and SIZE represents the array length i>j O isj O i+jSize-1 Oarrow_forward
