A minicomputer uses the first$-$fit system for memory management. Initially, it has one block of $256KB$ at address $0.$ The requests come in the following order:

$\backslash$table$[[$Arrival Time,Burst Time,Memory Needed$],[3,10,180],[6,4,90],[6,4,110],[13,1,150],[20,14,90],[24,10,10],[27,12,100],[35,10,50]]$

How many blocks are left at times $3,9,18,25,29,$ and $37,$ and what are their size and address?
