Uchburchak turini aniqlash

Uchburchakning tomonlari A, B, C berilgan. Uning turini satr sifatida qaytaring: "Teng tomonli" (uchala tomon teng), "Teng yonli" (aynan ikkitasi teng) yoki "Turli tomonli" (hammasi har xil).

func triangleType(A int, B int, C int) string {
    // ...
}

Misollar

Input: A=5, B=5, C=5
Output: "Teng tomonli"

Input: A=5, B=5, C=3
Output: "Teng yonli"

Input: A=3, B=4, C=5
Output: "Turli tomonli"

Maslahatlar

1. Avval uchala tomon tengligini (A == B && B == C) tekshiring.
2. Keyin juftliklar: `A == B
3. B == C
4. A == C`. Qolgani — turli tomonli.
