This input is on the project sheet [0 2 1 3 3 2 2 0 2 1 0 2 3 0] at t=7, the RAM should look like this right? [0₀ 2₀ 1₀ 3₀ 3₁ 2₁ 2₂ 0₁] then at t=13 the RAM would look like this right, since local LRU means that the next page replaces its previous page? [0₂ 2₃ 1₁ 3₂ 3₁ 2₀ 2₂ 0₃] Im not so clear on how out.txt should look like. The first 4 lines has to be the process page tables right? and then a fifth line shows the RAM content at the end (in this case at t=13)? So the out.txt of the example above should look like this? For the RAM content is it process, page, time stamp; or page, process, time stamp; ? 99, 99, 0, 7 99, 2, 99, 99 5, 99, 6, 1 99, 4, 3, 99 2,0,10;2,0,10;3,2,8;3,2,8;1,1,9;1,1,9;1,3,4;1,3,4;0,2,11;0,2,11;2,2,6;2,2,6;3,0,13;3,0,13; and another thing - if all processes has at least 1 page in the RAM by t=7 then the RAM will always look that way right? as in that only page numbers will change from that point onwards?

Thanks! But one more question, the project specifies this structure: struct { int process_id; int page_num; int last_accessed; } memory; Would i be penalised if i do not use that struct or can i do this project in any way I like?
