无语开头给空格gets输入不进去啊

#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
{
	char p[999],tet[99999];	
	scanf("%s\n", p);	
	gets(tet);//开头有空格，无语...再次无语，开头空格fgets输入不了
	int i = 0, j = 0,hr=1,num=0,first=-1;
	for (int i = 0; i < strlen(p); i++)
	{
		if (p[i] <= 'Z' && p[i] >= 'A')
		{
			p[i] += 32;
		}
	}
	for (int i = 0; i < strlen(tet); i++)
	{
		if (tet[i] <= 'Z' && tet[i] >= 'A')
		{
			tet[i] += 32;
		}
	}//统一小写
	while (!(tet[i] >= 'a' && tet[i] <= 'z'))
	{
		i++;
	}
	do
	{
		while (tet[j] != ' ')
