Given an equation, represented by words
on the left side and the result
on the right side.
You need to check if the equation is solvable under the following rules:
\n\nwords[i]
and result
are decoded as one number without leading zeros.words
) will equal to the number on the right side (result
).Return true
if the equation is solvable, otherwise return false
.
\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\n\n
\n
Constraints:
\n\n2 <= words.length <= 5
1 <= words[i].length, result.length <= 7
words[i], result
contain only uppercase English letters.10
.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:
\n\nwords[i]
和 result
都会被解码成一个没有前导零的数字。words
)等于右侧数字(result
)。 如果方程可解,返回 True
,否则返回 False
。
\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\n\n
