pascal's triangle code example

Example 1: program to print pascal triangle

#include <stdio.h>
int main() {
   int rows, coef = 1, space, i, j;
   printf("Enter the number of rows: ");
   scanf("%d", &rows);
   for (i = 0; i < rows; i++) {
      for (space = 1; space <= rows - i; space++)
         printf("  ");
      for (j = 0; j <= i; j++) {
         if (j == 0 || i == 0)
            coef = 1;
         else
            coef = coef * (i - j + 1) / j;
         printf("%4d", coef);
      }
      printf("\n");
   }
   return 0;
}

Example 2: pascal triangle c++

int pascal(int row, int col) {
  if (col == 0 || col == row) return 1;
  else if(col == 1 || (col + 1) == row) return row;
  else return pascal(row - 1, col - 1) + pascal(row - 1, col);
}

Example 3: Kth Row Of Pascal's Triangle

return a single integer denoting minimum xor value
