Code works fine on local eclipse. Returns Runtime Error on KickStart
platform. Any idea?
Round B 2020 - 1st problem:
package p3;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;
public class Solution {
public static int checkPeakPoints(int n, int[] arr) {
int peak = 0;
for (int i = 1; i < arr.length - 1; i++) {
if (arr[i] > arr[i - 1] && arr[i] > arr[i + 1])
peak++;
}
return peak;
}
public static void main(String[] args) {
Scanner in = new Scanner(new BufferedReader(new
InputStreamReader(System.in)));
int t = in.nextInt();
List<int[]> x = new ArrayList<int[]>();
for (int i = 1; i <= t; ++i) {
int n = in.nextInt(); // number of arr
int[] arr = new int[n];
for (int j = 1; j <= n; j++) {
int m = in.nextInt();
arr[j-1] = m;
}
x.add(arr);
}
StringBuilder sb = new StringBuilder();
for (int i = 0; i < x.size(); i++) {
int[] arr = x.get(i);
int sol = checkPeakPoints(arr.length, arr);
sb.append("Case #"+(i+1)+": "+sol+"\n");
}
System.out.println(sb.toString());
}
}
