For part $2-$ Data Processing

For this part you will build a data structure that keeps tract of every event type $($specifically the field call$\_$type$\_$final$\_$desc, unless that

field is blank then use the call$\_$type$\_$original$\_$desc field$).$ You will keep with each event type the total number of calls, the number of

calls where the dispatch time is $2$ minutes or less, from $3$ to $5$ minutes, $6$ to $10$ minute, and over $10$ minutes, and the on scene times are $2$

minutes or less, from $3$ to $5$ minutes, $6$ to $10$ minute, and over $10$ minutes. You will also selectively keep track of those times for either $3$

neighborhoods or police districts. Specifically $3$ values from the analysis$\_$neighborhood field or the police$\_$district field depending

on the command line parameters. To calculate dispatch time parse and subtract the received$\_$datetime from the dispatch$\_$datetime $.$

To calculate the on scene time parse and subtract the enroute$\_$datetime from the onscene$\_$datetime $.$

The output should be well formatted and columnar with clear headings. The event type should print our in alphabetical order. This is a

short example of what the output can look like:

Total Time was $37\mathrm{.}907384732$ seconds

You my use any data structure you like to hold the data as it is being processed, but it must be global $($i$.$e$.$ each thread will be adding

directly to it and mot merging at the end$)$ and you have to write the data structure code yourself, not using libraries. $($Note: using string

libraries for copying and comparing are okay$).$
