给你一个方程,左边用 words 表示,右边用 result 表示。

你需要根据以下规则检查方程是否可解:

如果方程可解,返回 True,否则返回 False

 

示例 1:

输入:words = ["SEND","MORE"], result = "MONEY"
输出:true
解释:映射 'S'-> 9, 'E'->5, 'N'->6, 'D'->7, 'M'->1, 'O'->0, 'R'->8, 'Y'->'2'
所以 "SEND" + "MORE" = "MONEY" ,  9567 + 1085 = 10652

示例 2:

输入:words = ["SIX","SEVEN","SEVEN"], result = "TWENTY"
输出:true
解释:映射 'S'-> 6, 'I'->5, 'X'->0, 'E'->8, 'V'->7, 'N'->2, 'T'->1, 'W'->'3', 'Y'->4
所以 "SIX" + "SEVEN" + "SEVEN" = "TWENTY" ,  650 + 68782 + 68782 = 138214

示例 3:

输入:words = ["THIS","IS","TOO"], result = "FUNNY"
输出:true

示例 4:

输入:words = ["LEET","CODE"], result = "POINT"
输出:false
