|

// EXERCISE: Observe the capacity growth
|
||||
//
|
||||
// Write a program that loops 10 million times to append an element
|
||||
// to a slice, on each step of the loop. Observe the capacity.
|
||||
//
|
||||
//
|
||||
// STEPS
|
||||
//
|
||||
// 1. Create a nil slice
|
||||
//
|
||||
// 2. Loop 10e6 times
|
||||
//
|
||||
// 3. On each loop step: Append an element to the slice
|
||||
//
|
||||
// 4. Only print the length and capacity of the slice everytime
|
||||
// the capacity changes.
|
||||
//
|
||||
// 5. Print also the growth rate by calculating the previous and
|
||||
// the current capacity.
|
||||
//
|
||||
//
|
||||
// EXPECTED OUTPUT
|
||||
//
|
||||
// len:0 cap:0 growth:NaN
|
||||
// len:1 cap:1 growth:+Inf
|
||||
// len:2 cap:2 growth:2.00
|
||||
// ... and so on.
