6. : For this problem a 2d array of ints represents the value of each block in a city. Each element in the array is a city block. The value of a block could be negative indicating the block is a liability to own. Complete a method that finds the value of the most valuable contiguous sub rectangle in the city represented by the 2d array. The sub rectangle must be at least 1 by 1. (If all the values are negative "the most valuable" rectangle would be the negative value closest to 0.) Note, for this method you may assume the given 2d array of ints will not cause your method to overflow or underflow the Java int data type.

Through the process of sedimentation,sediment is turned back to rock to form sedimentation.the process of sedimentation is: > deposition-where fragments were deposited into the river or sea under gravity or travelling agent such as wind or water. > sedimentation-the fragments deposited in the river sedimented and accumulate> compaction-the layers of fragments deposited undergoes compaction due to the weight if the upper layers> cementation-chemical substance of the fragments such as cement dissolved into the water and cement the other fragments together to form sedimentary rock.thus,cementation and compaction are the process.on the other hand, transformation only occur when a rock under goes metamorphism(compaction or extreme heat).while recrystillization occurs when a rock is melted and cooled down,which also requires metamorphism to take place.hope it !
