本文介绍了一种高效的算法，用于在一个特殊属性的矩阵中查找特定值。该矩阵每一行的整数从左到右递增排序，并且每行的第一个整数大于前一行的最后一个整数。通过一个例子说明了如何在这样的矩阵中查找目标值。
Write an efficient algorithm that searches for a value in an mn matrix. This matrix has the following
properties:
• Integers in each row are sorted from left to right.
properties:
• Integers in each row are sorted from left to right.
• The first integer of each row is greater than the last integer of the previous row.
For example, Consider the following matrix:
[
[1, 3, 5, 7],
[10, 11, 16, 20],
[23, 30, 34, 50]
]
Given target = 3, return true.
