The Pascals Triangle is just a triangular pattern of numbers. But what makes it interesting is how each number is built from the two numbers directly above it. The first row starts with a 1 at the top. Each row after that gets wider, and every number in the triangle is the sum of ...
Initialize the rows variable to an integer value you want for Pascal's triangle pattern. Use fmt.Scanln() to read and store the rows value. Using for loop: The condition is given inside an if statement and stop execution is mentioned once the condition is right. In the line 28 of the ...
