既然这道题只有一个测试点，那我选择直接打表

#include<iostream>
using namespace std;
const int N=1e5+10;
const int INF=0x3f3f3f3f;
int t,a,b;
string s;
int main()
{
    cin>>t;
    while(t--)
		cin>>a>>b>>s;
	cout<<"62 abcdefghiz\n2 11011100000100010111110010010110011111001001100011010010001\n\n10 1234567890123456789012345678901234567890\n16 3A0C92075C0DBF3B8ACBC5F96CE3F0AD2\n\n16 3A0C92075C0DBF3B8ACBC5F96CE3F0AD2\n35 333YMHOUE8JPLT7OX6K9FYCQ8A\n\n35 333YMHOUE8JPLT7OX6K9FYCQ8A\n23 946B9AA02MI37E3D3MMJ4G7BL2F05\n\n23 946B9AA02MI37E3D3MMJ4G7BL2F05\n49 1VbDkSIMJL3JjRgAdlUfcaWj\n\n49 1VbDkSIMJL3JjRgAdlUfcaWj\n61 dl9MDSWqwHjDnToKcsWE1S\n\n\n61 dl9MDSWqwHjDnToKcsWE1S\n5 42104444441001414401221302402201233340311104212022133030\n\n5 42104444441001414401221302402201233340311104212022133030\n10 1234567890123456789012345678901234567890";
    return 0;
