1. For this question, you will use the package.edusa.bst" a. When you execute the BSTTest class, the following the output is generated, this binary search is constructed on Student id. Sample output is given based on student id. Printing the Tree id=30, name=pqi, percentage=76.78 id=89, name=xyz percentage=69.89 id=90, name=yts, percentage=78.9 id=100, name=def, percentage=65.78 id=150, name=mno, percentage=98.76 id=175, name=bac, percentage=67.89 id=190, name=cab, percentage=50.25 id=200, name=abe, percentage=56.89 id=210, name=jkl, percentage=89.89 What changes you have to make so that the binary search tree is constructed on student percentage Printing the Tree id=190, name=cab, percentage=50.25 id=200, name=abe, percentage=56.89 id=100, name=def, percentage=65.78 id=175, name=bac, percentage=67.89 id=89, name=xyz, percentage=69.89 id=30, name=Pqr, percentage=76.78 id=90, name=yts, percentage=78.9 id=210, name=jkl, percentage=89.89 id=150, name=mno, percentage=98.76 Page 2 of 4 aximum Data Structures _CS204_ _Tuesday, 17 May, 2022 b. Write the implementation of findMaxPercentage() method which returns the maxim percentage of student in the BSTImpl. Sample output is given based on student id. Printing the Tree id=190, name=cab, percentage=50.25 id=200, name=abc, percentage=56.89 id=100, name=def, percentage=65.78 id=175, name=bac, percentage=67.89 id=89, name=xyz, percentage=69.89 id=30, name=pqs, percentage=76.78 id=90, name=yts, percentage=78.9 id=210, name=jkl, percentage=89.89 id=150, namemno, percentage=98.76 Maximum student percentage details are id=150, name=mno, percentage=98.76
