Problem:
 Score : 100 points    Problem Statement  A Hitachi string is a concatenation of one or more copies of the string hi .  For example, hi and hihi are Hitachi strings, while ha and hii are not.  Given a string S , determine whether S is a Hitachi string.      Constraints   The length of S is between 1 and 10 (inclusive).  S is a string consisting of lowercase English letters.         Input  Input is given from Standard Input in the following format:  S       Output  If S is a Hitachi string, print Yes ; otherwise, print No .        Sample Input 1 hihi      Sample Output 1 Yes  hihi is the concatenation of two copies of hi , so it is a Hitachi string.       Sample Input 2 hi      Sample Output 2 Yes       Sample Input 3 ha      Sample Output 3 No
