I have an array whose number of rows can vary but cols are 34. One of the cols, 12th, has values 0,1,2 & 3. There is no set pattern as to how many times any of them can occur in one such array. Also, there is no exact distribution of rows with 12th col = 0/1/2/3, it may happen that 4 rows have 0, next 10 rows have 1, next 7 rows have 2 and last three rows have 3. My requirement is, how to truncate the array based on 12th col value being, either 0 or 1 or 2 or 3. Any help is appreciated !
