Why this code is not accepted by Leetcode compiler? My program is running in netbeans. but leetcode compiler is not accepting it.
Here is my code:
import java.util.Arrays;
public class RemoveDuplicateFromArray {
public static int[] removeDuplicates(int[] nums) {
int temp, count = 0 ,l = 0;
temp = nums[0];
for(int i = 1; i < nums.length - (1 + l); i++ ) {
if(temp == nums[i]) {
count = count + 1;
for(int j = i; j < nums.length - count; j++){
nums[j] = nums[j+1];
}
i = i - 1;
} else {
temp = nums[i];
i = i ;
}
l = count;
}
nums = Arrays.copyOfRange(nums, 0, nums.length-count);
if(nums.length == 2){
if(nums[0] == nums[1]){
nums = Arrays.copyOfRange(nums, 0, nums.length-1);
}
}
return nums;
}
Here is my main mathod:
public static void main(String[] args) {
int[] nums = new int[] {1,1,1}; // showing error here.
System.err.println("nums lenght: " +nums.length);
int new_nums[] = removeDuplicates(nums);
for(int i : new_nums) {
System.err.print(i + " ");
}
}
}
The error is :
incompatible types: int[] cannot be converted to int.
