With linked allocation, each file is a linked list of disk blocks; the disk blocks may be scattered anywhereon the disk. The directory contains a pointer to the first and last blocks of the file.

C++ ARRAYS 3. Population In the Lithuanian register, the personal identification code data of the population is stored in the format SYYMMDDXXXX. Here: S- Gender: 3 (male, 1900-1999), 4 (female, 1900-1999), 5 (male, 2000-), 6 2000-), YY is the last two digits of the year of birth (00, 01, 02, 03, MM - month of birth number (01, 02, 03, ... 11, 12), DD - number of the date of birth (01.02, 03, ... 30, 31), XXXX - registration number (0001 ... 9999). Make a program that will find the dates of birth of the eldest Lithuanian man and woman and display them on the screen. The first line of the source data file contains the personal codes n (1 <n < 3000). Next, each line contains one code.
A File was sorted by key field, and then 10 records were stored in each block. Multi-level Indexing is made here, and 100 indexes are stored in each block. To find a specific record, the total number of block accesses is less than 4. Calculate the maximum number of records that make up this file.
