Web23 Oct 2024 · Program to generate Pascal’s Triangle. Problem Statement: Given an integer N, return the first N rows of Pascal’s triangle. In Pascal’s triangle, each number is the sum of the two numbers directly above it as shown in the figure below: Example 1: Input Format: N = 5 Result : 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1 Explanation: There are 5 rows in ... WebThe elements in the Pascal’s triangle can find out by finding the sum of the two adjoint elements in the preceding row. The formula to find the entry of an element in the nth row and kth column of a pascal’s triangle is given by ( n k ) = ( n-1 k-1 ) + ( n-1 k ), where n is a non-negative integer and k lies between and n. this means that n ≥ 0 and 0 ≤ k ≤ n.
