Question

用户输入一个数字，该数字将在数组中搜索。之后，他/她将输入数组的大小和元素。在编写解决方案时：

number_to_be_searched = gets.chomp #my input=>4
size_of_array = gets.chomp #input => 6
array = Array.new

Integer(size_of_array).times do
    str = gets
    str = Integer(str)
    array.push(str)
end

print array
if array.include? Integer(number_to_be_searched)
    print array.index(number_to_be_searched)
end

我收到以下错误：

：Integer（）的无效值“1 4 5 7 9 12”（ArgumentError）

Answer 1

print 'Number to be searched: '
number_to_be_searched = gets.chomp
print 'Enter size of array: '
size_of_array = gets.chomp
array = Array.new
Integer(size_of_array).times do  |i|
    print "Enter #{i+1}th number: "
    str = gets
    str = Integer(str)
    array.push(str)
end 

p "Numbers you Entered are #{array}"

if array.include? Integer(number_to_be_searched)

    p "Index of found number is : #{array.index(number_to_be_searched.to_i)}"
end

在“整数”中获取错误：Integer（）的值无效
