Write a method which takes an integer ‘N’ as argument, and generates the ‘Pascal triangle’ of height ‘N’, and returns it. ‘Pascal triangle’ is a triangular array of binomial coefficients. An example with N = 5 is shown below. Hint: The value of a non-boundary element is related to the elements above and above-left. Test the method in the ‘main’ method. 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 For problems asking for 'methods', you need to write the method, and the 'main' method which is used as a 'driver' to test the given method.

Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.
