4. Array (2) Advanced Applications and Characters and Character Arrays 1. Array-table-driven method-bool type Table-driven method is also called table-driven and table-driven method. “Table” is a very useful data structure that is discussed in almost all data structure textbooks. The table-driven approach is a method that allows you to look up information in a table […]

How to pack multiple object arrays into Xml (C#, bpel)
Nothing happened these past two days. I took a look at the code of my senior and found that he wrote a more interesting code. I will analyze and record it here. 1. Situation analysis There are five pieces of data in the picture above. To transmit these five pieces of data to the backend, […]

[ABC274Ex] XOR Sum of Arrays
section> Problem Statement For sequences $B=(B_1,B_2,\dots,B_M)$ and $C=(C_1,C_2,\dots,C_M)$, each of length $M$, consisting of non-negative integers, let theXOR sum $S(B,C)$ of $B$ and $C$ be defined as the sequence $(B_1\oplus C_1, B_2\oplus C_2, …, B_{M}\oplus C_{M})$ of length $M$ consisting of non-negative integers. Here, $\oplus$ represents bitwise XOR. For instance, if $B = (1, 2, […]
