Question

MATLAB code only! please show work on matlab

Cut the Pipes: (adapted from hackerrank.com)) The user will enter the length of several pipes as a vector (all positive integers). You must cut all the pipes into pieces using as few cuts as possible, but you can only make cuts the length of the smallest pipe left! For example, suppose you have six pipes of the following lengths: 655228 We can now make a cut of length 2 (the smallest pipe) from each of the six pipes. For the next cut operation, four pipes are left (of non-zero length): 4336 1 t cu ust be length 3 because 3 is the smallest stick left! You must repeat this proce unt crear no pipes left. Display to the user how many total cuts are needed to finish all th sticks. Program Inputs • Enter pipe lengths in (): - The user will always enter several positive whole numbers Program Outputs • XXX cuts are needed! - Replace XXX with the amount of cuts are taken to eliminate all sticks. Sample Output Test Case 1: Enter pipe lengths in [] : [1 2] 2 cuts are needed!

Answer 1

===================== matlab code is ================================================

pipes = input('Enter pipe length in []:');

m = 1;
cut=0;
while m~=0
pipes1 = pipes(pipes>0);
if length(pipes1)==0
m=0;
else
min_val = min(pipes1);
pipes1 = pipes1-min_val;
pipes = pipes1;
cut = cut+1;
end
  
end
fprintf('%d cuts are needed!\n',cut);

Screenshots of the code and the output:

-------------------------------------------------------------------------------------------------------------------------------------------------------

pipes = input('Enter pipe length in []:'); m = 1; cut=0; while m~=0 pipesl = pipes (pipes>0); if length (pipes1)==0 m=0; else min_val = min (pipesl); pipesl = pipesl-min_val; pipes = pipesl; cut = cut+1; end end fprintf('%d cuts are needed!\n', cut);

>> bisection Enter pipe length in [] : [1 2] 2 cuts are needed! >> bisection Enter pipe length in [] : [6 5 5 2 2 8] 4 cuts are needed!

======================================================= end======================

Note: bisection in the screenshots is filename i.e bisection.m :choose your own filename
