Hello, I am new to this platform. I’ve failed to submit two solutions. I get a runtime error on “Little Chef and Sums” question - the first question in the practice section. There must be something I’m missing. Please point it out. Thanks
I’m submitting this code:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class MainClass {
public static void main(String[] args){
try{
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String firstLine = br.readLine();
int testCasesCount = Integer.parseInt(firstLine);
for(int i = 0; i < testCasesCount; i++){
int arrayLength = Integer.parseInt(br.readLine());
String arrayStr = br.readLine();
String[] arrayStrArr = arrayStr.split(" ");
int[] arr = new int[arrayLength];
for(int j = 0; j < arrayLength; j++){
arr[j] = Integer.parseInt(arrayStrArr[j]);
}
int min = arr[0];
for(int j = 0; j < arrayLength; j++){
if(min > suffixSum(j, arr) + prefixSum(j, arr)){
min = suffixSum(j, arr) + prefixSum(j, arr);
}
}
System.out.println(min+1);
}
} catch(IOException e){
e.printStackTrace();
}
}
private static Integer suffixSum(int beginPos,int[] arr){
int sum = 0;
for(int i = beginPos; i < arr.length; i++){
sum += arr[i];
}
return sum;
}
private static Integer prefixSum(int beginPos, int[] arr){
int sum = 0;
for(int i = 0; i < beginPos; i++){
sum += arr[i];
}
return sum;
}
}
I also couldn’t submit this solution(although it is another question but in both the cases I’m getting correct answers but answers do not seem to submit) - Getting wrong answer on codechef but getting right output on my computer (Free ticket problem) - general - CodeChef Discuss
