Answer 2

Answer:

This is the algorithm for the question

1. Define a string or take input.
2. Two loops will be used to find the duplicate characters. Outer loop will be used to select a character and initialize variable count by 1.
3. Inner loop will compare the selected character with rest of the characters present in the string.
4. If a match found, it increases the count by 1 and set the duplicates of selected character by '0' to mark them as visited.
5. After inner loop, if count of character is greater than 1, then it has duplicates in the string.

Explanation:

string =input("Enter your string");  

 

print("Duplicate characters in a given string: ");  

#Counts each character present in the string  

for i in range(0, len(string)):  

   count = 1;  

   for j in range(i+1, len(string)):  

       if(string[i] == string[j] and string[i] != ' '):  

           count = count + 1;  

           #Set string[j] to 0 to avoid printing visited character  

           string = string[:j] + '0' + string[j+1:];  

 

   #A character is considered as duplicate if count is greater than 1  

   if(count > 1 and string[i] != '0'):  

       print(string[i]);
