此阵列中显示警报的状态。 时间格式如下：HH：MM：SS
[["red", "00:00:00"],
["orange", "00:00:02"],
["green", "00:00:05"],
["red", "00:00:07"],
["green", "00:00:27"],
["red", "00:00:28"],
["green", "00:00:29"]]
我想算一下次数＆＃34; red＆＃34;之后是＆＃34;绿色＆＃34;在10秒的时间内。
Step 1: Look for red
Step 2: IF Not last item
Compare with next item on array
ELSE Go to Step 4
Step 3: IF green,
time_difference = green_time - red_time
IF time_difference <= 10 seconds
count = count + 1
Go to Step 1
ELSE Go to Step 1
ELSE Go to Step 2
Step 4: Print Count
计数应为2

以下是您遇到问题的解决方案
array = [
["red", "00:00:00"],
["orange", "00:00:02"],
["green", "00:00:05"],
["red", "00:00:07"],
["green", "00:00:27"],
["red", "00:00:28"],
["green", "00:00:29"]
]
# iterating over first to second last element of array. Skipping the last element because we want to compare every element with its successor.
selected_result_set = array[0..-2].select.with_index do |arr, index|
# first comparing if current element (array) contains 'red' and its successor contains 'green'
if arr[0] == 'red' && array[index + 1][0] == 'green'
# comparing time difference here
(DateTime.parse(arr[1]).to_time - DateTime.parse(array[index + 1][1]).to_time) <= 10
end
end
# selected result will consist of the array of 'red' value which passes our condition
selected_result_set.count
