Tekislikda ikki nuqta orasidagi masofa

Tekislikda ikkita nuqtaning koordinatalari (x1, y1) va (x2, y2) berilgan. Ular orasidagi masofani toping: √((x2 − x1)² + (y2 − y1)²).

func solve(x1 int, y1 int, x2 int, y2 int) float64 {
    // ...
}

Misollar

Input: x1=0, y1=0, x2=3, y2=4
Output: 5.0

Input: x1=1, y1=1, x2=4, y2=5
Output: 5.0

Input: x1=-2, y1=3, x2=1, y2=7
Output: 5.0

Maslahatlar

1. Avval dx = x2 − x1 va dy = y2 − y1 ni hisoblang.
2. Masofa d = √(dx² + dy²).
