One of the typical situations is choosing an inefficient data structure or algorithm for a task. For example, in Go, if you need frequent search and insertion of elements, you can use slices ([]T), but with a large volume of data, insert and delete operations will have a complexity of O(n), which is inefficient.

The best solution in such cases is to use built-in maps (map), which provide amortized access and insertion times of about O(1).

An example of an incorrect solution:

var data []int
// Frequent addition and removal of elements in the middle of the slice

A correct solution:

dataMap := make(map[int]bool)
// Fast access and update of elements

Therefore, it is important to choose appropriate data structures, considering performance requirements.
