The input to the following algorithm is a positive integer. the goal is to find the digit in the hundreds place of the integer. (for example, if we input 28398, we want the algorithm to output 3.) below is the proposed algorithm, but the values of x and y are missing: step 1: divide the input by x. call the quotient and ignore the remainder. step 2: now divide by y. ignore the quotient and call the remainder step 3: return what x, y will allow this algorithm to correctly find the hundreds digit of the input? put x in the first blank and y in the second blank. note: we would say that has a quotient of 2 and a remainder of 1.

The first division should reduce the hundreds digit to the units digit by dividing by 100.  Ignoring remainder means ignoring the previous units and tens digits.
The second division, where we keep the remainder is to extract the units digit by ignoring the quotient.  So we divide by 10.  The discarded digits are the tens and higher digits.

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 !
