// EXERCISE: Observe the capacity growth
|
|
//
|
|
// Write a program that appends elements to a slice
|
|
// 10 million times in a loop. Observe how the capacity of
|
|
// the slice changes.
|
|
//
|
|
//
|
|
// STEPS
|
|
//
|
|
// 1. Create a nil slice
|
|
//
|
|
// 2. Loop 1e7 times
|
|
//
|
|
// 3. On each iteration: Append an element to the slice
|
|
//
|
|
// 4. Print the length and capacity of the slice "only"
|
|
// when its capacity changes.
|
|
//
|
|
// BONUS: Print also the growth rate of the 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.
