Assume that a file temperature.txt contains the recordings of the highest temperate on a given day at a given location. A sample contents of a file temperature.txt is listed below. Assume that the file contains only data and no headers listed above data. temperature.txt location number temperature date 24-DEC-2020 2 34 17-JAN-2021 1 25 25-DEC-2021 33 18-JAN-2021 3 10 11-DEC-2020 23 Information about the locations is stored in a file location.txt. Each location belongs to one city and a city may have many locations where a temperature is recorded. A sample contents of a file location.txt is listed below. Assume that the file contains only data and no headers listed above data 1 location.txt location number city Dapto 2 Sydney 3 Singapore 4 Dapto 5 Singapore Your task is to explain how to implement a MapReduce application, that finds he highest temperature ever recorded in each city. The application must return the names of all cities together with the highest temperature ever recorded in each city. You must specify the parameters (if any) of your application and the key-value data in the input and output of the Map and Reduce stages. There is no need to write Java code, however, if you like it then it is all right to do so. Very precise explanations in plain English or in a pseudocode will do
