Question

USE MATLAB: USE FOR AND WHILE LOOPS

Write a program to check whether a number is a palindrome or not. Palindromes are numbers that read same backward and forward.

Test Data : Input a number: 121

Expected Output :

121 is a palindrome number.

Answer 1

n = input("Input a number: ");
inputValue = n;
reversedInt = 0;
for i=1:inputValue
    reversedInt=reversedInt*10+mod(n,10);
    n=floor(n/10);
    if(n==0)
        break;
    end
end
if(reversedInt==inputValue)
    fprintf("%d is a palindrome number.\n",inputValue);
else
    fprintf("%d is not a palindrome number.\n",inputValue);
end

n = input("Input a number: ");
inputValue = n;
reversedInt = 0;
while(n!=0)
    reversedInt=reversedInt*10+mod(n,10);
    n=floor(n/10);
end
if(reversedInt==inputValue)
    fprintf("%d is a palindrome number.\n",inputValue);
else
    fprintf("%d is not a palindrome number.\n",inputValue);
end
