Given two 2D arrays, array1 and array2, find the indices of the first occurrence of a submatrix in array1 that matches array2. A submatrix is a rectangular section of the larger matrix. The matching is determined by comparing the values in the corresponding positions of the submatrix and array2.
For example:
array1 =... | codefeedback | [

I have this problem : Delete Columns to Make Sorted II
Description are as below: You are given an array of `n` strings `strs`, all of the same length.
We may choose any deletion indices, and we delete all the characters in those indices for each string.
For example, if we have `strs = ["abcdef","uvwxyz"]` and deletio... | codefeedback | [
