Pseudocode Functions and Array Operations

The video tutorial covers the A-level paper, focusing on a pseudocode question involving a function called 'Too Many'. The function counts strings in an array and returns a boolean based on a condition. The tutorial explains the implementation, testing, and simplification of the function. It also covers modifications for a 2D array and checks specific conditions. The video concludes with a preview of the next tutorial.

What is the main focus of the video tutorial?

• A-Level paper pseudocode questions

• IGCSE syllabus overview

• Mathematics problem-solving

• Physics experiments

What does the 'too many' function return if the count of matching strings is greater than the maximum value?

• The count value

• An error message

• True

• False

Which type of search is used in the 'too many' function?

• Binary search

• Linear search

• Hash search

• Depth-first search

How is the return statement optimized in the 'too many' function?

• By removing the function

• By using a direct boolean evaluation

• By adding more conditions

• By using a loop

What change is made to the global array in Part B?

• It is reduced to 100 elements

• It is expanded to 200 elements

• It is converted to a 2D array

• It is sorted

In the 2D array, what must be true for a string to be counted?

• The search string must be a number

• The search string must match in both columns

• The row index must be odd

• The row index must be even

What is checked to determine if a row is even?

• Row mod 4 equals zero

• Row mod 5 equals zero

• Row mod 2 equals zero

• Row mod 3 equals zero

Which columns are checked for the search string in the 2D array?

• Column 1 and Column 3

• Column 2 and Column 4

• Column 1 and Column 2

• Column 3 and Column 4

What is the purpose of using 'Row mod 2' in the pseudocode?

• To check if the row is a multiple of 3

• To check if the row is odd

• To check if the row is even

• To check if the row is a multiple of 5

What is the significance of the condition 'Row mod 7 equals zero'?

• It checks for even rows

• It checks for rows that are multiples of 7

• It checks for odd rows

• It checks for rows that are multiples of 5
