After the first puzzle appears, go to the`Day01.kt` and for each`part1` and`part2`classes, provide an algorithm implementation using theprovided`input` data loaded from the`day01.txt` file.

When the first puzzle appears, go to the`Day01.kt` and for each`part1` and`part2`functions, provide an algorithm implementation using the`input` data loaded from the`src/Day01.txt` file.

This input data is common for both parts, and you can find it on the bottom of each day on the[Advent of Code][aoc] page.

To read the input data as a list of strings, you can go with the`String.ints()` utility method provided in the[`utils.kt`][file:utils] file, like:

This file also contains the`String.md5()` method for generating MD5 has out of the given string and expects more helper functions for the sake of the[KISS principle][kiss].
80

81
-
To check if everything works as expected during the development, you can use the test data and answers within each day's story and provide them for your`DayTest` test implementation.
82
-
You may want to run such a test case by clicking the_Test All Days_ Run/Debug Configuration provided in the top-right toolbar or check the test result for each day separately.

To go with the next day, place the`day02.txt` file into the`resources` with relevant input data, create`Day02.kt` file with the class implementation:
70
+
Each puzzle describes some test conditions, a small portion of the information that helps check if the produced value for the given test input is valid.
71
+
To handle that case, you can put such an input into a separated file and perform a standard assertion against the output, like:
85
72
86
73
```kotlin
87
-
classDay02 :Day(2) {
88
-
// ...
74
+
funmain() {
75
+
val testInput= readInput("Day01_test")
76
+
assert(part1(testInput)==13)
89
77
}
90
78
```
91

92

Then just provide tests for the second day in a similar manner:
80
+
The final result of your algorithm will be printed on the screen so that you can pass it to the Advent of Code website.
81
+
82
+
To go with the next day, place the`Day02.txt` file into the`src` with relevant input data and create`Day02.kt` file with a similar code scaffold:

83
94
84
```kotlin
95
-
classDay02Test :DayTest() {
96
-
97
-
overrideval day=Day02()
85
+
funpart1(input:List<String>):Int {
86

return0
87

}

@Test

-
overridefun`Part 1`() {
101
-
assertEquals(0, day.part1("test_input"))// check against test input
102
-
assertEquals(0, day.part1())// check solution against input data
103

}
89

funpart2(input:List<String>):Int {
90

return0
