Plot Geographical Data on a Map Using Python Plotly. First, the default argument m=1 is awkward, which leads to the odd if m > n+1: and if m == 1: test conditions. Given an input n (provided however is most convenient in your chosen language), generate the first n rows of Pascal's triangle. Both the algorithm and flowchart are generate Pascal’s triangle in standard format as per the number of rows entered by the user. We take an input n from the user and print n lines of the pascal triangle. Take in the number of rows the triangle should have and store it in a separate variable. Each number is found by adding two numbers which are residing in the previous row and exactly top of the current cell. You may assume that n is an integer inclusively between 1 and 25. 3.
