1.

Write pseudo-code to implement a function that takes a 1D array of integers and a positive integer 'n' as input. The function should calculate the sum of the first 'n' elements of the array and store the result in a variable called 'sum'. Assume the array is indexed from 0.

Function: CalculateSum(array, n)

Input: 1D array of integers (array), positive integer (n)

Output: Integer (sum)

Initialize sum = 0

For i = 0 to n - 1 do:

sum = sum + array[i]

End For

Return sum

2.

Consider an array of integers representing sales figures for a week. Write pseudo-code to determine if the total sales for the week are greater than 1000. The pseudo-code should include a loop to iterate through the array and a conditional statement.

Pseudo-code:

Input: An array of integers representing daily sales figures (e.g., sales[0], sales[1], sales[2], sales[3], sales[4], sales[5], sales[6]).

Initialize:
- total_sales to 0

Calculate Total Sales:
- For each sales figure in the sales array:
  - Add the current sales figure to total_sales.

Check if Total Sales Exceeds 1000:
- If total_sales is greater than 1000:
  - Display "Total sales exceed 1000".
- Else:
  - Display "Total sales do not exceed 1000".

Write pseudo-code to implement a function that takes a 2D array of integers and two positive integers, 'row' and 'col', as input. The function should calculate the product of all the elements in the specified row and store the result in a variable called 'product'. Assume the array is indexed from 0 for both rows and columns.

Function: CalculateRowProduct(array, row, col)

Input: 2D array of integers (array), positive integers (row, col)

Output: Integer (product)

Initialize product = 1

For i = 0 to col - 1 do:

product = product * array[row][i]

End For

Return product
