Question

The method removeDupes is intended to remove duplicates from array a, returning n, the number of elements in a after duplicates have been removed. For example, if array a has the values {4, 7, 11, 4, 9, 5, 11, 7, 3, 5} before removeDupes is called, then after duplicates are removed, a will be {4, 7, 11, 5, 9, 3} and 6 will be returned.Consider the following three implementations of RemoveDupes. I. public static int removeDupes (int [ 1 a) int n-a.length; for (int i-0, icn; i+M int current- a [il: int j i+1; while (jcn)K if (currentaulK alil aln-1) return n; Il. public static int removeDupes (int [] a)t int n-a.length; for (int i-0; ikn; i++ int current a [il for (int j-0; j

Answer 1

Answer:

public int removeDupes(int[]a){

int n =0;

for(int x =0;x<a.length;x++){

for(int y=0;y<a.length;y++){

if(a[x]==a[y]){

n++;

}

}

int left = a.length-n;

return left;

}

}
