Given numRows, generate the first numRows of Pascal‘s triangle.
For example, given numRows = 5,
Return
[ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1] ]
#include<stdio.h> #include<stdlib.h> int **generate(int numRows){ int **p=(int **)malloc(sizeof(int *)*numRows); int i,j; for(i=0;i<numRows;i++){ p[i]=(int *)malloc((i+1)*sizeof(int)); p[i][0]=p[i][i]=1; for(j=1;j<i;j++) p[i][j]=p[i-1][j-1]+p[i-1][j]; } return p; } void main() { int n=4,i,j; int **p=generate(n); for(i=0;i<n;i++){ for(j=0;j<=i;j++){ printf("%d",p[i][j]); } printf("\n"); } }
