Using C, 5) Upper Triangle : Display the Upper Triangle of the above 5x5 2D Array along with its Sum and the Mean 6) Lower Triangle : Display the Lower Triangle of the above 5x5 2D Array along with its Sum and the Mean 7) Symmetric: Use the obtained Lower Triangle matrix to generate a Symmetric matric. [The Lower Triangl of the obtained Symmetric Array should be same as the result of 6] Sample Output for Part 2 (single trial): 13945 23421 69212 23411 23739 The Sum is = 89 The Mean is = 3.56 Upper Triangle 13945 03421 00212 00011 00009 The Sum is = 48 The Mean is = 1.92 Lower Triangle 10000 23000 69200 23410 23739 The Sum is = 57 The Mean is = 2.28 Symmetric 12622 23233 69247 23413 23739 The Sum is = 91 The Mean is = 3.64
