Li Ding submitted a Comment to Problem 830. Fill a zeros matrix

In the problem, line 3 "square matrix" should have the "square" removed; plural of index will be indices... Nevertheless I like the problem especially with all those forbidden words.

Li Ding submitted a Comment to Problem 690. Remove the two elements next to NaN value

The term "next to NaN" would generally be considered as the one right before and the one right after NaN, if existing. Also the problem failed to say that NaN themselves need to be removed.

Re-wording is needed for this problem. Here is how I interpreted the problem: 1. "common row, column entry" means a same value at the same row-column location 2. zeros don't count. You need to check for non-zeros...
