Sequence: A sequence is a list or array of related values stored as a collection. Examples of sequences are Matrices and vectors.

Matlab example:

var1 = 1:10

Here var1 is a sequence of integers 1 to 10.

Selection Structure: Selection structures are constructs used to decide the flow of the program, i.e. to select one of the possible alternatives based on some conditions. These structures are commonly implemented as If-else statements in most programming languages.

Matlab Example:

b = 5;

if b%2 ==0
disp("b is even")
else
disp("b is odd")
end

Output: b is even

Repetition Structure: These are constructs to repeatedly process one or more instructions until some condition is met. In most languages, these are available as loops such as for loop and while loop.

Matlab Example:

for i = 1:5

disp(i)

end

The above code will print numbers 1 to 5, each number in a new line as shown below:

Ques 1 to 5:

1. ans = 0 (False) because 5 is not less than 1

2. ans = 1 (True) as 1 is less than 5

3. ans = [ 0,0,0,0,0] as all 5 values of x are not smaller than y

4. ans = [ 0,0,0,0,1] as only last value of x which is 5 is less tha last value of y which is 6

5 ans = 1 and ans = 0 because x is equal to 2 and x is not equal to 7
