I'm trying to delete the highest and lowest numbers of the array int[] ary4 = {2,17,10,9,16,3,9,16,5,1,17,14};
it works on this specific one but when I'm changing the numbers it just doesn't do what my intentions are. I know how to do it a different way but I want to solve it with this method.
public static int[] elimAll(int[] a) {
int c = 1;
int g = 1;
int[] b = a.clone();
Arrays.sort(b);
for (int i = 0; i < b.length; i++){
if (i == 0) {
if (b[i] < b[c]) {
b[i] = 0;
c++;
}else{
if (b[i] < b[c] && b[i] < b[i-1]) {
b[i] = 0;
c++;
}
}
}
}
for (int i = 0; i < b.length; i++){
if (i == b.length-1 || i == b.length-2){
if (b[i] >= b[b.length-1] || b[i] >= b[b.length-2]){
b[i] = 0;
g++;
}
}else {
if (b[i] > b[i + 1]) {
b[i] = 0;
g++;
}
}
}
return b;
}
Here is one way. It does not require any sorting.
int[] ary4 = {2,17,10,9,16,3,9,16,5,1,17,14};
System.out.println("Before: " + Arrays.toString(ary4));
int[] result = elimAll(ary4);
System.out.println(" After: " + Arrays.toString(result));
prints (you can see the two 17's and the lone 1 were removed)
Before: [2, 17, 10, 9, 16, 3, 9, 16, 5, 1, 17, 14]
After: [2, 10, 9, 16, 3, 9, 16, 5, 14]
Explanation
highest
and lowest
values.public static int[] elimAll(int[] array) {
int highest = Integer.MIN_VALUE;
int lowest = Integer.MAX_VALUE;
for (int val : array) {
highest = Math.max(highest, val);
lowest = Math.min(lowest,val);
}
int k = 0;
int [] result = new int[array.length];
for(int val : array) {
if (val != highest && val != lowest) {
result[k++] = val;
}
}
return Arrays.copyOf(result, k);
}
