# Non-deterministic Map Iteration

- ID: go-map-iteration-without-sort
- Severity: MEDIUM
- CWE: CWE-330 (CWE-330)
- Languages: Go

## Description

Converts map to slice without sorting, producing non-deterministic output.

## Detection Message

Map iteration order in Go is non-deterministic. This code converts a map
to a slice without sorting, which will produce different orderings on
each execution.


## Remediation

Add sorting after collecting keys/values from the map:

```go
// Before (non-deterministic):
result := make([]string, 0, len(myMap))
for key := range myMap {
    result = append(result, key)
}
return result  // Order varies!

// After (deterministic):
result := make([]string, 0, len(myMap))
for key := range myMap {
    result = append(result, key)
}
sort.Strings(result)  // Always same order
return result
```

For non-string types, use sort.Slice:
```go
sort.Slice(result, func(i, j int) bool {
    return result[i].Name < result[j].Name
})
```
