#include<bits/stdc++.h>
using namespace std;
#define ll long long
const int mod=998244353;
int n;ll m;
int dp[70][70][2],c[70][70];
int cp(int x,int y,int z){
    if(x<y)return 0;
    if(x>y)return 1;
    return z;
}
int main(){
    scanf("%d%lld",&n,&m);m-=(1ll<<(n-1));
    if(m<0){puts("0");return 0;}
    c[0][0]=1;
    for(int i=1;i<=n;i++){
        c[i][0]=1;
        for(int j=1;j<=i;j++)c[i][j]=(c[i-1][j-1]+c[i-1][j])%mod;
    }
    dp[0][0][1]=1;
    for(int i=0;i<60;i++){
        int e=min(i+1,n);
        for(int j=0;j<=n;j++)for(int o=0;o<2;o++)if(dp[i][j][o]){
            for(int k=0;k<=e;k++)
            (dp[i+1][(k+j)>>1][cp((m>>i)&1,(k+j)&1,o)]+=1ll*dp[i][j][o]*c[e][k]%mod)%=mod;
        }
    }
    printf("%d",dp[60][0][1]);
    return 0;
}

这程序好像有点Bug,我给组数据试试?
