如何将5×4网格代码改为长尾词？

本文共计473个文字，预计阅读时间需要2分钟。

为了将代代码转换为如下的5x4网格，我们可以使用以下方法：

+---+---+---+---+| | | | |+---+---+---+---+| | | | |+---+---+---+---+| | | | |+---+---+---+---+| | | | |+---+---+---+---+

对于5x5网格，并且要表示为+ 5 + 4的格式，我们可以这样写：

+---+---+---+---+---+| | | | | |+---+---+---+---+---+| | | | | |+---+---+---+---+---+| | | | | |+---+---+---+---+---+| | | | | |+---+---+---+---+---+

对于5+x+5的网格，并且尚未定义，我们可以先假设一个格式：

+---+---+---+---+---+| | | | | |+---+---+---+---+---+| | | | | |+---+---+---+---+---+| | | | | |+---+---+---+---+---+| | | | | |+---+---+---+---+---+

请注意，这里的+和-表示网格的边，而|表示网格的列分隔符，内部用空格表示网格的单元格。

那么如何使代码成为如下所示的5x4网格。我目前得到一个5x5的网格并且未定义。00000

//Grid size: result will be n*n cellsconst GRID_SIZE = 5;const grid = ["0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0", "0"];// Ship Locationsconst shipLocatiOns= ["3", "9", "15"];let guess; //Entered valuelet count = 0; //counter for roundsdo { //We'll loop indefintely until the user clicks cancel on prompt //Construct prompt using string template (multiline) const prpt = `Round #${++count}${printGrid()}Enter a Number Between 0-19`; guess = prompt(prpt); if (!guess //Stop when cancel was clicked const hit = shipLocations.indexOf(guess) >= 0; console.log(`At round ${count}, cell ${guess} is a ${hit ? 'hit': 'miss'}`); grid[guess] = hit ? '1' : 'X';} while (guess || guess === 0); //Must have an exit condition/** Pretty-print the grid **/function printGrid() { let res = ""; for (let r = 0; r 回答

在“printGrid”中，行 (r) 和列 (c) 都循环到 5 (GRID_SIZE)。如果你想要一个 5x4 的网格，你将需要不同的行和列大小值：

ROW_GRID_SIZE=4;COL_GRID_SIZE=5;

并改变你的循环：

for (let r = 0; r
