GIven 9 balls all of which weigh the same except for one, what is the minimum of weighings necessary to find the ball weighs more (or less).
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.
Given an input string S write a function which returns true if it satisfies S = nT. Basically you have to find if a given string can be represented from a substring by iterating it “n” times. n >= 2 An example would suffice – Function should return true if 1) S = “abab” 2) S = “abcdabcd” 3) S = “abcabcabc” 4) S = “zzxzzxzzx” Function should return false if 1) S = “abac” 2) S = “abcdabbd” 3) S = “abcabcefg” 4) S = “zzxzzyzzx” It would be easy to understand if you can give an algo instead of saying use kmp or suffix tree or… I came up with O(n*n) solution. Wondered how to do in O(n)
