如何输入整数值数组，以preceeding行+列的值？ [英] How to input integer value to an array, based preceeding row + column values?

问题描述

有关这个项目之后，我应该把输入的格式如下：R1C5 + 2，其内容为在餐桌上，一排5列1，加2或者格式为：R1C2C3-5，这曰：在餐桌上，排1月2日至3日柱，减去5这是假设表中所有数字是最初所有0

。

在哪里我离开的：

我无法找到一个方法来检测一个+或 - 要么在表中加/减值。此外，在提供一系列允许多个补充提供两个C的或R级的时候。例如：R1R5C2C3 + 2（行范围1 - 5，列范围2 - 3，加2）

下面是下列code：

 提出'请输入：
X = gets.chompCOL = []
行= []x.chars.each_sli​​ce（2）{| U | U [0] ==R？行＆LT;＆LT; U [1]：COL＆LT;＆LT; U [1]}p山坳
p行把最大＃在排阵：＃{} row.max
把最大＃在列阵列：＃{} col.max#must在返回值big_row = row.max.to_i
big_col = col.max.to_i
表= Array.new（big_row）{Array.new（big_col）}
 

我谢谢大家的帮助！

解决方案

你的功课，先生。

 提出'请输入：
X = gets.chompCOL = []
行= []
标志=''
VAL =''x.chars.each_sli​​ce（2）做| U |
  大小写u [0]
  当R则
    行＆LT;＆LT; U [1]
  'C'然后当
    COL＆LT;＆LT; U [1]
  当+， - 
    标志，VAL = U [0]，U [1]
  其他
    把输入无效。
    出口
  结束
结束big_row = row.max.to_i
big_col = col.max.to_i
表= Array.new（big_row）{Array.new（big_col）}＃初始化表为全零
table.map！做|行|
  row.map！ {|山口| 0}
结束rows_range = row.length == 1？行[0] ...行[0]：行[0] ...行[1]
cols_range = col.length == 1？ COL [0] .. COL [0]：COL [0] .. COL [1]table.each_with_index做|排，RI |
  如果row​​s_range.include？ （RI + 1）.to_s
    row.each_with_index做|关口，CI |
      如果cols_range.include？ （CI + 1）.to_s
        表[RI] [CI] =（符号+ VAL）.to_i
      结束
    结束
  结束
结束＃用于填充表字段中。
填充= 4＃表
table.each做|一行|
  row.each做|山口|
    打印＃{col.to_s.rjust（填充）}
  结束
  打印\\ n
结束
 

For this following project, I am supposed to take input in the following format : R1C5+2 , which reads it as "in the table, Row 1 Column 5 ,add 2. Or in this format : R1C2C3-5 , which reads : "in the table, Row 1 Column 2-3, subtract 5. This is assuming that all numbers in the table are initially all 0.

Where I left Off:

I am having trouble finding a way to detect for a "+" or "-" to either add/subtract values in the table. Also, in providing a range to allow multiple additions when provided two C's or R's. For example: R1R5C2C3+2 (Row Range 1 - 5, Column Range 2 - 3, add 2).

Here is the following code:

puts 'Please input: '
x = gets.chomp

col = []
row = []

x.chars.each_slice(2) { |u|  u[0] == "R" ? row << u[1] : col << u[1] }

p col
p row

puts "Largest # in Row array: #{row.max}"
puts "Largest # in Columns array: #{col.max}" #must be in "" to return value

big_row = row.max.to_i
big_col = col.max.to_i


table = Array.new (big_row) { Array.new(big_col) }

I thank you all for the help!

解决方案

Your homework, sir.

puts 'Please input: '
x = gets.chomp

col = []
row = []
sign = ''
val = ''

x.chars.each_slice(2) do |u|
  case u[0]
  when 'R' then
    row << u[1]
  when 'C' then
    col << u[1]
  when '+', '-'
    sign, val = u[0], u[1]
  else
    puts 'Invalid input.'
    exit
  end
end

big_row = row.max.to_i
big_col = col.max.to_i
table = Array.new (big_row) { Array.new(big_col) }

# Initialize table to all zeros
table.map! do |row|
  row.map! { |col| 0 }
end

rows_range = row.length == 1 ? row[0]..row[0] : row[0]..row[1]
cols_range = col.length == 1 ? col[0]..col[0] : col[0]..col[1]

table.each_with_index do |row, ri|
  if rows_range.include? (ri + 1).to_s
    row.each_with_index do |col, ci|
      if cols_range.include? (ci + 1).to_s
        table[ri][ci] = (sign + val).to_i
      end
    end
  end
end

# Padding for fields in table.
padding = 4

# Table
table.each do |row|
  row.each do |col|
    print "#{col.to_s.rjust(padding)}"
  end
  print "\n"
end
