As the link to the full data file is now broken, I've had to confine myself to the 6 lines shown in the task description for testing purposes.
<lang scala>// version 1.2.0
import java.io.File
fun main(args: Array<String>) {
val rx = Regex("""\s+""")
val file = File("readings.txt")
var count = 0
var invalid = 0
var allGood = 0
var map = mutableMapOf<String, Int>()
file.forEachLine { line ->
count++
val fields = line.split(rx)
val date = fields[0]
if (fields.size == 49) {
if (map.containsKey(date))
map[date] = map[date]!! + 1
else
map.put(date, 1)
var good = 0
for (i in 2 until fields.size step 2) {
if (fields[i].toInt() >= 1) {
good++
}
}
if (good == 24) allGood++
}
else invalid++
}
println("File = ${file.name}")
println("\nDuplicated dates:")
for ((k,v) in map) {
if (v > 1) println(" $k ($v times)")
}
println("\nTotal number of records : $count")
var percent = invalid.toDouble() / count * 100.0
println("Number of invalid records : $invalid (${"%5.2f".format(percent)}%)")
percent = allGood.toDouble() / count * 100.0
println("Number which are all good : $allGood (${"%5.2f".format(percent)}%)")
}</lang>
{{out}}
<pre>
File = readings.txt
Duplicated dates:
1991-03-31 (2 times)
Total number of records : 6
Number of invalid records : 0 ( 0.00%)
Number which are all good : 4 (66.67%)
</pre>
