Select one option to show which of the following best represents the input and the final calculated output variable representing the result of the algorithm in Figure 1.
Figure 1
constant BLOCK_SIZE ← 4096
constant METADATA_SIZE ← 128
OUTPUT 'Enter the size of the file in bytes'
fileSize ← USERINPUT
usableSpace ← BLOCK_SIZE - METADATA_SIZE
blocksNeeded ← 0
REPEAT
fileSize ← fileSize - usableSpace
blocksNeeded ← blocksNeeded + 1
UNTIL fileSize ≤ 0
Input: blocksNeeded, Output: usableSpace
Input: fileSize, Output: blocksNeeded
Input: usableSpace, Output: fileSize
Input: BLOCK_SIZE, Output: blocksNeeded
