// EXERCISE: Print daily requests
|
||
//
|
||
// You've got a requests log for a system in a slice: `reqs`.
|
||
// The log contains the total requests counts per 8 hours.
|
||
//
|
||
// The reqs slice is a single-dimensional slice but you need
|
||
// to group the daily into a slice named: `daily`.
|
||
//
|
||
// Please follow the instructions inside the code to solve
|
||
// the exercise.
|
||
//
|
||
//
|
||
// EXPECTED OUTPUT
|
||
//
|
||
// Please run `solution/main.go` to see the expected
|
||
// output.
|
||
//
|
||
// go run solution/main.go

|
||
// #1: DAILY REQUESTS DATA
|
||
//
|
||
// . The system collects and groups the requests per 8 hours
|
||
//
|
||
// . So there are 3 requests totals per day
|
||
//
|
||
// . Your code should be robust enough to work with
|
||
// insufficient data. For example, in the last day
|
||
// there are only two request totals: 100 and 150.
|
||
//
|
||
// So, don't forget to handle that edge case as well.
|
||
//
|
||
// . Uncomment the code below and start
|
||
//
|
||
|
||
// reqs := []int{
|
||
// 500, 600, 250,
|
||
// 200, 400, 50,
|
||
// 900, 800, 600,
|
||
// 750, 250, 100,
|
||
// 100, 150,
|
||
// }
|
||
|
||
//
|
||
// #2: Group the `reqs` per day into a slice named: `daily`
|
||
//
|
||
// . Create the daily slice using the `make` function
|
||
//
|
||
// . Anticipate the length argument to the make function using this data:
|
||
//
|
||
// + The length of the reqs slice
|
||
// + There are 3 requests totals per day
|
||
// + There are residual elements (the last day)
|
||
//
|
||
// ! So, do not blindly allocate a slice.
|
||
//
|
||
// ! Allocate the slice efficiently with the exact size needed.
|
||
//
|
||
// . Then append to it the daily requests in a "loop"
|
||
//
|
||
|
||
//
|
||
// #3: Print the header:
|
||
//
|
||
// Day Requests
|
||
// ====================
|
||
//
|
||
|
||
//
|
||
// #4: Print the data per day along with the totals:
|
||
//
|
||
// 1 500
|
||
// 1 600
|
||
// 1 250
|
||
// --------------------
|
||
// 1350 --> Print the daily total requests
|
||
//
|
||
// 2 200
|
||
// 2 400
|
||
// 2 50
|
||
// --------------------
|
||
// 650
|
||
//
|
||
// 2000 --> Also print the grand total
|
||
|
||

|
||
// ❤️ NOTE ❤️
|
||
//
|
||
// If you could't solve this challenge. Please do not get discouraged.
|
||
//
|
||
// Look at the solution, then try to solve it again. This is valuable too.
|
||
//
|
||
// Then ️change the request data, the number of requests per day (now it's 3), etc
|
||
// and then try to solve it again.
