In this post, we will see how to count repeated characters in a string.
Step 1: Declare a String and store it in a variable.
Step 2: Use 2 loops to find the duplicate characters. Outer loop will be used to select a character and initialize variable count to 1.
Step 3: Inner loop will be used to compare the selected character with remaining characters of the string.
Step 4: If a match found, it increases the count by 1.
Step 5: After completion of inner loop, if count of character is greater than 1, then it has duplicates in the string.
Step 6: Print all the repeated characters along with character count
Step 7: End
Input: "welcome to the world of python programming" Output: Duplicate characters in a given string: w - 2 e - 3 l - 2 o - 6 m - 3 t - 3 h - 2 r - 3 p - 2 n - 2 g - 2
string = "welcome to the world of python programming"; print("Duplicate characters in a given 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; string = string[:j] + '0' + string[j+1:]; if(count > 1 and string[i] != '0'): print(string[i]," - ",count);
