The Pascal triangle can be used to compute the coefficients of the terms in the expansion of (a + b)n. Write a function that creates a two-dimensional matrix representing the Pascal triangle. In a Pascal triangle, each element is the sum of the element directly above it and the element to the left of the element directly above it (if any). A Pascal triangle of size 7 is shown below 10 15 10 20 15 6 In the above example, the first element of row[o] and the first two elements of row[1] are set to 1. Then each of the following rows, up to the maximum size, arc set with a loop as shown in the following pseudocode: Algorithm PascalTriangle i pascal[0][0] 1 2 pascal[1][0] = 1 3 pascal [1][1] = 1 4 prevRow 5 currRow 6 loop (currRow
