When we apply the mergesort on a 12-element array, how many comparisons do we need for the worst case? Ans:

in java ecplise . Implement a program that randomly generates 10 integers from -100 to 100,stores them in a 1D array, and finds their maximum value. Calculate theexecution time of finding a maximum. Repeat the test for 10,000 and10,000,000 numbers. Provide your results in the form of a table below andprovide a small summary. Implement a Java program that will populate a 5x5 matrix with randomlygenerated integers from 0 to 100.(1) print your matrix in a table form.(2) modify your code to multiply all even numbers by 10 and print the matrix.Your output of questions (1) and (2) should match the format of the followingsample outputs:

Two words (spelt in uppercase) are similar if and only if all letters in the 1st word are in the 2nd word and all letters in the 2nd word are in the 1st word; including the same number of duplications. For example, ABBA and BABA are similar; however, BABA and BAAA are not similar. To check two words which are similar, we can use two integer arrays, each has 26 elements (as we have 26 letters), you can assume that 1st array element stores the number of letter 'A', 2nd array element stores the number of letter 'B', and so on. What you need to do now is to check whether the two integer arrays are equal to decide whether the two words are similar. We propose following UML for this question: O TwoWords - String word1 -String word2 O Exam_Q4 +TwoWords0 - static Scanner input +TwoWords(String word1, String word2) O+TwoWords(TwoWords tw) O+ String getWord10 O+ static void main(String args) O+ String getWord20 O+void setinfo(String word1, String word2) O -intj countinfo (String word) O+boolean…

A computer is printing out subsets of a 3 element set (possibly including the empty set). 1) How many different subsets are there? 1 2) At least how many sets must be printed to be sure of having at least 2 identical subsets on the list? 3) At least how many identical subsets are printed if there are 25 subsets on the list?
