第一次被笔试输入恶心到头疼
我绷不住了,今晚的笔试做的恶心,这个输入是有病吗?为什么不给输入数组的行数和列数,还是子符串类型,为什么不搞核心代码模式呢?我想问一下!!!输入改成数组改半天,顺便有没有大佬知道这样该怎么搞,还得先判断数组行数和列数吗?
import java.util.Scanner;
public class Juren0923 {
static int max =0;
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
String s = sc.nextLine();
System.out.println(getMax(s));
}
private static int getMax(String s) {
int ans=0;
int[][] grid= new int[?][?];??????
int hang =0;
int lie=0;
for (int i = 0; i < s.length(); i++) {
if(s.charAt(i)-'0'>=0&&s.charAt(i)-'0'<=9){
grid[hang][lie] = s.charAt(i)-'0';
lie++;
}else if(i>0&&s.charAt(i)==','&&s.charAt(i-1)==']'){
lie=0;
hang++;
}else{
continue;
}
}
dfs(grid,0,0,ans);
return max;
}
private static void dfs(int[][] grid,int x,int y,int ans){
if(x>=grid.length||y>=grid[0].length){
return ;
}
if(x== grid.length-1&&y==grid.length-1){
max = Math.max(ans,max);
return;
}
ans += grid[x][y];
dfs(grid,x+1,y,ans);
dfs(grid,x,y+1,ans);
} #笔试#
