Question

PLEASE USE MATLAB

This is a basic problem that illustrates the concept of strings. A palidrome is a string of characters that is read the same forwards as it is backwards. For example, racecar' is a palindrome; reversing the order of the characters leaves the string unchanged. Write a otherwise. function called isPalindrome that accepts one input and returns one output. The input str is a string of characters, and the output is 1 if str is a palindrome, For example isPalindrome('racecar') ans 1 isPalindrome('Racecar') %the function should be case-sensitive ans = You may assume the input string contains only letters. Your function may not use flip, flipud or fliplr. Your Function function isPal = isPalindrome (str) %YOUR CODE HERE. Finish this line. n is the numberr of characters in the string n isPal true; %initialize output as 1 ii 1;%index of str while ii <floor (n/2) %floor rounds down in str contains an odd number of characters. Only go through the first half of str if %YOUR CODE HERE. Finish the if-statement: "if the iith character of str does not equal its mirror image" isPal false; to check any ther characters end ii ii +1 %still looping? then increase the index 18 11 end 12 end 13 Code to call your function 1 isPalindrome('racecar') isPalindrome('Racecar) isPalindrome(' dad ") isPalindrome(goggledygookkoogydelggog ')

Answer 1

Explanation :

We will take string from user and will go through each character of first half of string and will compare it with its mirror counter part. If there is any mismatch, we will return the false or 0 otherwise true or 1.

Code:

function isPal = isPalindrome(str)
%initiating the function

n = length(str);
%Finding length of string

isPal = true;
%initiating the answer as true or 1;

ii = 1;
%initiating the index as 1

while ii<=floor(n/2)
%to go through only first half of the string

if str(ii)~= str(n-ii+1);
%Comparing the mirror images
  
isPal = false;
%Changing the answer if the condition is satisfied
  
return
%Getting out of loop if condition is satisfied
  
end
  
ii = ii+1;
%Increasing the index after evry loop to consider next char
end

end
