Design an algorithm to find the first unique element in an array.
Question was "Given a pattern and a string input - find if the string follows the same pattern and return 0 or 1. Examples: 1) Pattern : "abba", input: "redblueredblue" should return 1. 2) Pattern: "aaaa", input: "asdasdasdasd" should return 1. 3) Pattern: "aabb", input: "xyzabcxzyabc" should return 0. I saw someone else had a similar question, but it was much much easier as the other candidate was given spaces between words to help identify individual words to pattern match.
1. pattern question n=1 * *** n=2 * *** * * ***** n=3 * *** * * ***** * * * *******
Implement a function for determining the validity of a string. The string is valid if parentheses are correctly distributed within the string.
Write a function in language of your choice that takes in two strings, and returns true if they match. Constraints are as follows: String 1, the text to match to, will be alphabets and digits. String 2, the pattern, will be alphabets, digits, '.' and '*'. '.' means either alphabet or digit will be considered as a "match". "*" means the previous character is repeat 0 or more # of times. For example: Text: Facebook Pattern: F.cebo*k returns true
Given a m*n grid starting from (1, 1). At any point (x, y), you has two choices for the next move: 1) move to (x+y, y); 2) move to (x, y+x); From point (1, 1), how to move to (m, n) in least moves? (or there's no such a path)
