To find the duplicate words from the string, we first split the string into words. We count the occurrence of each word in the string. If count is greater than 1, it implies that a word has duplicate in the string. In above example, the words highlighted in green are duplicate words.

It is often called ‘slicing’. It follows this template: string[start: end: step] Where, start: The starting index of the substring. The character at this index is included in the substring. If start is not included, it is assumed to equal to 0. end: The terminating index of the substring. The character at this index is NOT included in the ... You can use collections to find repeating characters: import collections freq = collections.Counter("abcda") for k in freq: if freq[k] > 1: print k # prints "a" break If you want only to find if there are repetitions (without finding the repeated characters): Like many other popular programming languages, strings in Python are arrays of bytes representing unicode characters.

Print duplicate characters from a given string in C++. Problem statement. A user enters a string of any length. Write a C++ program to print duplicate characters from that string. The find() method finds the first occurrence of the specified value. The find() method returns -1 if the value is not found. The find() method is almost the same as the index() method, the only difference is that the index() method raises an exception if the value is not found. (See example below) Nov 14, 2011 · One of the most common string interview questions: Find the first non-repeated (unique) character in a given string.
