Use nested for...loops to create a (6×6) matrix in which the value of an element is three times its row number minus four times its column number provided the row number is greater than the column by 1. Otherwise, the element of the matrix is equal to 0.

aolve algorithm Suppose that you are attending a one day conference in which several lectures are presented in parallel sessions e, more than one lecture may by running at the same timej. Lectures may be of different lengths. The lectures schedule is given to you in an array L such that Ld is the D of a lecture, L stort is the starting time of that lecture and Lend is the end time of that lecture. If you attend a lecture, you must atmtend it from the beginning until the end of it lyou are not allowed to amend lectures partialy. You want to amend as many lectures as possible. a) Give the pseudocode of an algorithm that takes as input the array Land finds the maximum number of lectures that you can attend. You can assume that dthe starting times and end times are integers representing time. The conterence sarts at time 0 and ends at some times. If you need to use a binary search algorithm or a sorting algorithm you can just calwithout gving s peudocode. fyou need to use any other…

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
