WebJul 7, 2024 · The original method does two things in the same recursive method. This is confusing. So I changed it to two recursive methods. This helps because part of the complexity of the original was figuring out whether it was printing a line or a triangle. This replaces one complex method with three simple methods.

This is a fully functional implementation of a program to ask the user for a location on Pascal's Triangle, but I kind of cheated by expanding the base case to include row 0 and the 1st and last columns.

WebDec 15, 2024 · 2. Use Recursion. We can print Pascal's triangle using recursion with the formula nCr: n ! / ( ( n – r ) ! r ! ) 3. Avoid Using Recursion. Another way to print Pascal's triangle without recursion is to use binomial expansion. We always have the value 1 at the beginning of each line, then the value of k at the (n) line and the (i) position ... WebNov 20, 2024 · A couple of points, in Pascal triangle: The leftmost and rightmost element of every row is 1. Every row contains the number of columns same as the row number. So, I can say - if (n == i i == 0) //i.e. if ( (row == col) (col == 0)) return 1; return 1; could be terminating condition of the recursive function.
