Implement a magic directory with buildDict, and search methods. For the method buildDict, you'll be given a list of non-repetitive words to build a dictionary. For the method search, you'll be given a word, and judge whether if you modify exactly one

9.3 A magic index in an array A[0.. .n-1] is defined to be an index such that A[i] = i. Given a sorted array of distinct integers, write a method to find a magic index, if one exists, in array A.FOLLOW UPWhat if the values are not distinct? 这道题定义了一个魔
题目 小 N 最近在沉迷数学问题. 对于一个数字串 S,如果可以将它划分成两个数字 A.B,满足: 1. S=AB. 2. A.B 均不包含前导 0. 3. B 是 A 的倍数,且B / A是完全立方数. 那么小 N 就认为该划分是一个“好划分”. 如对于数字串“11297”,(11, 297)就是一个“好划分”. 如果一个数字串 S 至少有两个“好划分”,那么小 N 就认为 S 是一个“魔法串”. 如数字串“1335702375”就是一个“魔法串”,其“好划分”有(1, 335702375)和
