Lab Assignment: Dynamic Arrays

This task consists of two blocks, where different methods of handling dynamic arrays are to be implemented: one-dimensional arrays and jagged arrays. Below is the general approach for implementing each block in C#.

Block 1: One-dimensional Arrays

Input and Initialization of Array:

• A method is implemented to input data either from the console, txt file or by generating it randomly.

Method for Array Transformation:

• A method is created to change the size of the array.
  • Manual creation of a new array using new: A new array is created, and the necessary elements from the previous array are copied.

Removal of Elements:

• For each variant of element removal (e.g., the first even element, the last negative element), the following steps are performed:
  • Check if the element exists for removal.
  • Perform a shift of elements to ensure there are no "gaps" in the array.
  • After removal, change the size of the array to match the new number of elements.

Insertion of Elements:

• Elements are inserted into the array at a specified position.
• Inserting elements requires shifting the remaining elements of the array.

Implementation of Handling Variants:

• Necessary operations are performed, such as:
  • Insert the minimum value at the beginning and the maximum value at the end of the array.
  • Modify the array according to specific conditions.

Block 2: Jagged Arrays

Input of Jagged Array:

• A jagged array is an array of arrays. An array of arrays is used, where each inner array may have a different number of elements.

Processing of Jagged Array:

• For each variant, rows are added or removed from the jagged array.
• Reference reassignment is used to shift rows in the array, avoiding complex element copying.

Checking Conditions:

• Before removal or insertion, it is checked if there are rows or elements available to perform the operation.

Insertion and Removal of Rows:

• Rows are inserted at the beginning or end of the jagged array by modifying references to the corresponding arrays.
• Removal of rows is done by shifting elements or simply reassigning references.

Implementation of Handling Variants:

• For example, rows containing certain elements (minimum, maximum values) are removed, empty rows are inserted after every even row, and so on.
