class Solution: def construct2DArray(self, original: List[int], m: int, n: int) -> List[List[int]]: # 如果长度不等于目标二维数组的大小,则直接返回空数组 if len(original) != m * n: return [] # 定义二维数组 ans: List[List[int]] = [[0] * n for _ in range(m)] # 初始化...
Explanation: The constructed 2D array should contain 2 rows and 2 columns. The first group of n=2 elements in original, [1,2], becomes the first row in the constructed 2D array. The second group of n=2 elements in original, [3,4], becomes the second row in the constructed 2D array...

2c to Fig. 2d is for fitting the timing of CNOTs into the order rule. When qubits are set on edges, the number of steps in transferring information from data qubits to syndrome qubits increases. However, thanks to this transformation, CNOTs are executed in parallel; thereby, the circuit ...
Garbage in, garbage out. If you want the output to be wrapped in a class declaration, you have to wrap the input in a class declaration. The grammar must be wrapped in an LLLPG block. Use "LLLPG (lexer)" for a lexer and "LLLPG (parser)" for a parser. The difference between the...
provided by the input argument 'defs', call the function legacy_code() again with the first input set to 'sfcn_cmex_generate'. The S-functions call the legacy functions in simulation. The source code for the S-functions is in the files: * sfun_filterV1.c * sfun_filterV2.c ...

You may not alter the values in the nodes, only nodes itself may be changed. Only constant memory is allowed. For example, Given this linked list: 1->2->3->4->5 For k = 2, you should return: 2->1->4->3->5 For k = 3, you should return: 3->2->1->4-...

其实题目是一样的,同样是问是不是一个doubled array,而且已经是even number,数可以是负数,只需要返回true 或者false。 答案思路也是一样的。这里要用absolute来排序。 class Solution { public: bool canReorderDoubled(vector<int>& arr) { unordered_map<int, int> c; for (int i : arr) { c[i]++;...
