In java language using arrays This method examines the two-dimensional array of integersidentified by the first parameter, whose length (number of rows,also the number of students) is the second parameter, while thethree columns in the array represent the scores for threedifferent tests.The test scores for each student (one row of three grades) arecombined to find the average score for each student. The integerreturned is the number of students with a test average less than 70. @param numStudents, the number of students who took the three tests@param theArray, a 2-D array of integer scores@return, the number of test averages below a score of 70*/public static int testAverage(double[][] theArray, int numStudents){int NUM_TESTS = 3; // your work here // loop though theArray, computing each student's average // your work here// return count of averages below 70.0 // your work here
Given an array of integers, print a sum triangle from it such that the first level has all array elements. From then, at each level number of elements is one less than the previous level and elements at the level is be the Sum of consecutive two elements in the previous level. Input The single line of input contains an array of integers, each of it is separated by space Output Triangle form that has been created from the input array Sample Input1 12345 Sample Output1 48 20 28 8 12 16 3579 12345
