Sizga m x n o'lchamdagi ikki o'lchamli matrix berilgan. Uning barcha elementlarini spiral tartibda (tashqaridan ichkariga qarab soat mili yo'nalishida) qaytaring.
Matritsa to'rtburchak bo'lishi mumkin (m ≠ n). Yuqori chap burchakdan boshlab: o'ngga → pastga → chapga → tepaga, va shu tartibda ichkariga.
