Cargo Container Report.
You will be producing a program which will allow the user to generate the container report on the following page in
Container Number order or Ship Name order. The program will also the user to lookup the data for any given Container
by number. The % cargo weight is the percentage of the cargo of the gross weight (cargo weight/gross weight), % total
is the percentage of the cargo for that container of the total amount of cargo unloaded (cargo weight for the container /
total cargo unloaded. Hint: you are expected to use methods for your calculations.
The accompanying file has the data for the containers unloaded today. The data includes
container number int
ship name. String
tare weight of the container (empty weight) int
the gross weight (container plus the cargo). Int
You will need to computer the cargo weight as the gross weight minus the tare weight.
If you have issues reading the data with the String, you may remove the String. However, you will lose points.…

- PHP Write a reduce function Write a function reduce($arr, $func) that takes an array and a function as a parameter. The reduce function should apply the parameter function to each element of the array in succession to produce a single result. Note: the current result should always be the first parameter to the function and the next element of the array should always be the second parameter. You may not use the PHP function array_reduce in your solution. For example, the result of the following should be 10. function myMax($current, $new) { return $current < $new ? $new : $current; } $arr = array(10, 5, 3, 5, 1, 2, 5, 7, 4); print("Max: " . reduce($arr, 'myMax') .arrow_forwardJAVA ONLYPlease create a code that checks if 'user' favourite game is in the top 3 games. if the game is in the top 3 then it should say: "common favourite game" if else then "uncommon favourite game"code: TOP_3_GAMES = {'', 'CALL OF DUTY', 'LEAGUE OF LEGENDS', 'VALORANT'}arrow_forwardPlease answer this questions and show the work and explain how you got the answer!arrow_forward
