Question

Please help me with these question. I am having trouble understanding what to do

Programming language (HTML, CSS, JavaScript)

For each question draw a flowchart (with pen and paper). And includes it postconditions and preconditions

Ex 14) Devise an algorithm to input an integer greater than 1 as n, and output the first n values of the Fibonacci sequence. In Fibonacci sequence, the first two values are 0 and 1 and other values are sum of the two values preceding it. For instance, if the input is 4, the program should print 0, 1, 1, 2. As another example, if the input is 9, the program should output 0, 1, 1, 2, 3, 5, 8, 13, 21.

Ex 15) Devise an algorithm to input a positive integer, n, – and by using ‘*’ characters – output the figure below that has n rows, with 3 ‘*’ characters in the top row and 3*n characters in the last row. For instance, if input is 5, the figure on the left (and if the input is 12, the  figure on the right) should be generated by the program.
