Please help me with this MATLAB question using a FOR and/or WHILE loop

In Activity 1.11, we introduced the concept of the injury severity score (ISS). The ISS is a medical score to assess trauma severity and is calculated as follows: Each injury is assigned an abbreviated injury scale (AIS) score in the range [05] which is allocated to one of six body regions (head, face, chest, abdomen, extremities, and external). Only the highest AIS score in each body region is used. The three most severely injured body regions (i.e., with the highest scores) have their AIS scores squared and added together to produce the ISS. Therefore the value of the ISS is always between 0 and 75 . Write a MATLAB script m-file to compute the ISS, given an array of 6 AIS scores, which represent the most severe injuries to each of the six body regions. Test your code using the array [304530], for which the ISS should be 50
