Shaxmat figurasi yurishini tekshirish

Shaxmat taxtasida figura turi fig (1 — Rook (ladya), 2 — Bishop (fil), 3 — Queen (farzin), 4 — Knight (ot)) va ikkita katak (x1, y1) hamda (x2, y2) berilgan (1–8). Taxtada boshqa figuralar yo'q deb hisoblab, figura bir yurishda birinchi katakdan ikkinchisiga o'ta olsa true, aks holda false qaytaring. Katak o'zgarmasa ((x1,y1) = (x2,y2)) yurish yo'q — false.

func chessMove(fig int, x1 int, y1 int, x2 int, y2 int) bool {
    // ...
}

Misollar

Input: fig=1, x1=1, y1=1, x2=1, y2=5
Output: true

Input: fig=2, x1=1, y1=1, x2=4, y2=4
Output: true

Input: fig=4, x1=1, y1=1, x2=2, y2=3
Output: true

Maslahatlar

1. dx = |x2 - x1|, dy = |y2 - y1|.
2. Ladya: dx == 0 yoki dy == 0. Fil: dx == dy. Farzin — ladya yoki fil yurishi. Ot: (dx, dy) — (1, 2) yoki (2, 1).
