Leetcode 118 Pascal's triangle Solution in java | Hindi Coding Community

 

Given an integer rowIndex, return the rowIndexth (0-indexed) row of the Pascal's triangle.

Example 1:

Input: rowIndex = 3

Output: [1,3,3,1]

class Solution {

public:

    vector<int> getRow(int rowIndex) {

        vector<int> ansArray(rowIndex+1,0);

        ansArray[0] = 1;

       

        for (int i = 1; i <= rowIndex; i++)

            for (int j = i; j > 0; j--)

                ansArray[j] = ansArray[j] + ansArray[j - 1];

       

        return ansArray;

    }

};
