{ "data": { "question": { "questionId": "2632", "questionFrontendId": "2546", "categoryTitle": "Algorithms", "boundTopicId": 2068893, "title": "Apply Bitwise Operations to Make Strings Equal", "titleSlug": "apply-bitwise-operations-to-make-strings-equal", "content": "

You are given two 0-indexed binary strings s and target of the same length n. You can do the following operation on s any number of times:

\n\n\n\n

For example, if s = "0110", you can choose i = 0 and j = 2, then simultaneously replace s[0] with (s[0] OR s[2] = 0 OR 1 = 1), and s[2] with (s[0] XOR s[2] = 0 XOR 1 = 1), so we will have s = "1110".

\n\n

Return true if you can make the string s equal to target, or false otherwise.

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "1010", target = "0110"\nOutput: true\nExplanation: We can do the following operations:\n- Choose i = 2 and j = 0. We have now s = "0010".\n- Choose i = 2 and j = 1. We have now s = "0110".\nSince we can make s equal to target, we return true.\n
\n\n

Example 2:

\n\n
\nInput: s = "11", target = "00"\nOutput: false\nExplanation: It is not possible to make s equal to target with any number of operations.\n
\n\n

Constraints:

\n\n\n", "translatedTitle": "执行逐位运算使字符串相等", "translatedContent": "

给你两个下标从 0 开始的 二元 字符串 starget ,两个字符串的长度均为 n 。你可以对 s 执行下述操作 任意 次:

\n\n\n\n

例如,如果 s = \"0110\" ,你可以选择 i = 0j = 2,然后同时将 s[0] 替换为 (s[0] OR s[2] = 0 OR 1 = 1),并将 s[2] 替换为 (s[0] XOR s[2] = 0 XOR 1 = 1),最终得到 s = \"1110\"

\n\n

如果可以使 s 等于 target ,返回 true ,否则,返回 false

\n\n

 

\n\n

示例 1:

\n\n
输入:s = \"1010\", target = \"0110\"\n输出:true\n解释:可以执行下述操作:\n- 选择 i = 2 和 j = 0 ,得到 s = \"0010\".\n- 选择 i = 2 和 j = 1 ,得到 s = \"0110\".\n可以使 s 等于 target ,返回 true 。\n
\n\n

示例 2:

\n\n
输入:s = \"11\", target = \"00\"\n输出:false\n解释:执行任意次操作都无法使 s 等于 target 。\n
