MATLAB Program for UNIQUE WORD

A string is said to be 'Unique' if none of the letters present in the string are repeated. Write a program to accept a string and check whether the string is Unique or not.

Input: COMPUTER

Output: Unique String

Input: APPLICATIONS

Output: Not a Unique String

We assume that the input String contains only ASCII characters (which includes all letters, numbers and special symbols that can be typed using the keyboard).

Prerequisite:

CODE to check UNIQUE String or not:

clc;

x=input('Enter the string:');

y=double(x);

l=length(y);

for i=1:length(y)

    if(y(i)>=97 && y(i)<=122)

        y(i)=y(i)-32;

    end

end

a=sort(y);

t=1;

for i=1:(length(a)-1)

    m=a(i);

    n=a(i+1);

    if(m~=n)

        t=t+1;

    end

end

if(t==l)

    disp('Yes');

else

    disp('No');

end
