Explanation / Answer

Solution :

1)

close all;
clear all;
clc;

disp('Begin problem 1');
a = [1 -2 2 0 -3 3 4];
b = [-1 2 -3 4 -5 6 -1];
c=0;
n=7;
m=b(n);
while n>=0
[m,n]=confuse1(m,n,a,b);
c=c+1;
end

disp(['Number of loops is ',num2str(c)]);
disp('bye bye')

function [m,n] = confuse1(m,n,a,b)
  
if m>4
disp('Branch 1')
temp = a(n-1)*b(n+1);
n = n-5;
disp('temp');
elseif (n<=2 | n==4)
disp('Branch 2')
m=m+6;
temp=a(n+1)*b(m-1);
disp(temp);
else
disp('Branch 3')
temp=a(n)*b(m+3);
n=abs(n-3);
disp(temp);
end

%************************This gives output :

2)

close all;
clear all;
clc;

message1 = 'eating good';
message2 = 'makes studying satisfying';

total = [message1,' food ',message2];
s1 = ['Be ',message1(8:11)];
s2 = '';
for i=[7,8,2,11]
s2 = [s2 ,message2(i)];
end
s3 = [message2(16:17),message2(21),message2(4)];
disp(total)
disp(s1)
disp([s2 ,' ',s3])

%**************************

The output is :

eating good food makes studying satisfying
