Given an equation, represented by words on the left side and the result on the right side.

\n\n

You need to check if the equation is solvable under the following rules:

\n\n\n\n

Return true if the equation is solvable, otherwise return false.

\n\n

 

\n

Example 1:

\n\n
\nInput: words = ["SEND","MORE"], result = "MONEY"\nOutput: true\nExplanation: Map 'S'-> 9, 'E'->5, 'N'->6, 'D'->7, 'M'->1, 'O'->0, 'R'->8, 'Y'->'2'\nSuch that: "SEND" + "MORE" = "MONEY" ,  9567 + 1085 = 10652
\n\n

Example 2:

\n\n
\nInput: words = ["SIX","SEVEN","SEVEN"], result = "TWENTY"\nOutput: true\nExplanation: Map 'S'-> 6, 'I'->5, 'X'->0, 'E'->8, 'V'->7, 'N'->2, 'T'->1, 'W'->'3', 'Y'->4\nSuch that: "SIX" + "SEVEN" + "SEVEN" = "TWENTY" ,  650 + 68782 + 68782 = 138214
\n\n

Example 3:

\n\n
\nInput: words = ["LEET","CODE"], result = "POINT"\nOutput: false\nExplanation: There is no possible mapping to satisfy the equation, so we return false.\nNote that two different characters cannot map to the same digit.\n

给你一个方程,左边用 words 表示,右边用 result 表示。

\n\n

你需要根据以下规则检查方程是否可解:

\n\n\n\n

如果方程可解,返回 True,否则返回 False

\n\n

 

\n\n

示例 1:

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

示例 2:

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

示例 3:

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

示例 4:

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