Question

for matlab

Function Name: ​vineCompilation

Inputs:

1. (​char​) The first vine quote

2. (​char​) The second vine quote

Outputs:

1. (​char​) A “compilation” of the vines

Background:

It’s Sunday afternoon and you’re hanging out in your lounge, finishing off your Sprite Cranberry. Your Mom FriendTM (Jared, 19) walks in and yells at you for drinking soda for breakfast. Aggravated, you YEET the empty can down the hall as Jared drags you to the kitchen to make breakfast. You open the fridge to find some tortillas, eggs, and wow! Look at all that chicken! Jared says he could make the perfect breakfast tacos if he only had some fre sha voca do. You guys get your fre sha voca dos and Jared makes you some scrumptious breakfast tacos. To repay him, you make him a compilation of his favorite vines, with a little help from your friend MATLAB!

Function Description:

Given two string inputs, swap the first and second halves of the first input and sort the second input in reverse alphabetical order. Then, “compile” the two strings by inserting the first string into the odd indices of the output, and the second string into the even indices of the output. If one string is longer than the other, add exclamation points to the end of the shorter string so the strings are the same length.

Example:

vine1= ' '
vine2= ' '
compilation = vineCompilation(vine1, vine2)
vine1 → ' '
vine2 → ' '
compilation → '​p​v​t​s​y​r​.​o​ ​o​Y​h​E​f​E​e​T​d​!​c​T​a​h​a​i​ ​s​ ​​​c​!a​ ​!​n​!​ ​!​e​!m​ ​!​'

Notes:

• ● If the first string's length is an odd number, split it into two unequal halves with the first half being longer than the second, then swap them.

  Hints:

• ● The ​sort()​ function can take in two parameters.

• ● The ​ceil()​ function may be useful.

Answer 1

Hi, please find the answer below:

Code:

Output:

Firstly, the length of both the inputs is found. The first string is swapped with first and second halves. The second string is sorted in descending order of alphabets. The longer string is found and '!' symbols are added to the end of shorter strings. Finally, the output is formed by adding the first string in odd indices and second string in even indices. I have added comments for easy understanding. I have attached screenshots of the function code. Create a new file to call the function with input arguments like:

op = vineCompilation('abcdjkl','efgh')

Please find the editable code below:

function output = vineCompilation(string1,string2)
len_string1 = length(string1); %Finding the lengths of input strings
len_string2 = length(string2);
mid = ceil(len_string1/2); %Middle index of first string

str1 = strcat(string1(mid+1:len_string1),string1(1:mid)) %Swapping first and second half of input1
string2 = sort(string2,'descend') %sorting second string in reverse alphabetical order

output_length = len_string1+len_string2;
%Finding the largest string and appending ! to the end
if(len_string1<len_string2) %second string is larger
diff = len_string2-len_string1;
for i=len_string1+1:len_string1+diff
str1(i)='!'; %appending ! to the end
end
disp(str1)
output_length = len_string2 *2; %length of output
  
elseif(len_string1>len_string2) %first string is larger
diff = len_string1-len_string2;
for i=len_string2+1:len_string2+diff
string2(i)='!'; %appending ! to the end
end
disp(string2)
output_length = len_string1 *2; %length of output
end

ind1 = 1; %start index for first string
ind2 = 1; %start index for second string
%Creating output
for j = 1:output_length
if(rem(j,2)==0) %even indices
output(j)=string2(ind2); %adding second string
ind2 = ind2+1; %incrementing the second string index
else %odd indices
output(j)=str1(ind1); %adding first string
ind1 = ind1+1; %incrementing the first string index
end
end

I hope the explanation is clear and is useful in your understanding. Thank you.
