Python: Find the maximum length of a substring of unique character in a given string
24. Longest Uniform Substring
Write a Python program to find the maximum length of a substring in a given string where all the characters of the substring are the same. Use the itertools module to solve the problem.
Sample Solution:
Python Code:
import itertools
def max_sub_string(str1):
return max(len(list(x)) for _, x in itertools.groupby(str1))
str1 = "aaabbccddeeeee"
print("Original string:",str1)
print("Maximum length of a substring with unique characters of the said string:")
print(max_sub_string(str1))
str1 = "c++ exercises"
print("\nOriginal string:",str1)
print("Maximum length of a substring with unique characters of the said string:")
print(max_sub_string(str1))
Sample Output:
Original string: aaabbccddeeeee Maximum length of a substring with unique characters of the said string: 5 Original string: c++ exercises Maximum length of a substring with unique characters of the said string: 2
