微众银行5月11日笔试
有胖友做了今天的微众笔试吗，求教最后一题思路，这是我前两题的代码
public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int n = scan.nextInt();
int m = scan.nextInt();
int l = scan.nextInt();
int r = scan.nextInt();
int[] a = new int[n];
int[] b = new int[m];
for(int i = 0; i < n; i++) a[i] = scan.nextInt();
for(int i = 0; i < m; i++) b[i] = scan.nextInt();
Arrays.sort(a);
Arrays.sort(b);
int cnt = 0;
for(int i = 0; i < n; i++) {
if(a[i] > r) continue;
for(int j = 0; j < m; j++) {
if(a[i] + b[j] <= r && a[i] + b[j] >= l) cnt++;
if(a[i] + b[j] > r) break;
}
}
System.out.print(cnt);
scan.close();
}
} public class Main {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
long t = scan.nextLong();
for(long i = 0; i < t; i++) {
System.out.println(helper(scan.nextLong(), scan.nextLong(), scan.nextLong()));
}
scan.close();
}
static long helper(long a, long b, long x) {
if(a == x) return Math.abs(x - b);
if(b == x) return Math.abs(x - a);
if((a < x && b > x) || (b < x && a > x)) {
return Math.abs(x - b) + Math.abs(x - a);
}else {
if(Math.abs(x - a) <= Math.abs(x - b)) {
return Math.abs(b - a) + Math.abs(a - x);
}else {
return Math.abs(b - a) + Math.abs(b - x);
}
}
}
