Rotation means we have to shift each character either in a forward direction or backward direction. Forward direction means right rotation (Or anticlockwise) and backward direction means left rotation (Or clockwise). In this problem, we have given a string of size n. Our task is to find the minimum number of the character to be changed to check whether it is possible to the make left rotation and right rotation of a string the same. Let's see examples with explanations below to understand the problem in a better way. Input 1 str = "wxyz" Output 1 2 Explanation The ... Read More

Contractions play a significant role in informal writing and speech, in the field of Natural Language Processing (NLP), it is often necessary to expand contractions to improve text understanding and processing. contractions are shortened versions of words or phrases that combine two words into one. For example, "can't" is a contraction of "cannot, " and "it's" is a contraction of "it is." While contractions are commonly used in everyday communication, they can pose challenges for NLP systems due to their ambiguity and potential loss of context. In this article, we will explore the techniques and challenges associated with expanding contractions ... Read More
