Question
Write a static method minGap that takes an integer array as a parameter and that returns the minimum gap
between adjacent values in the array. The gap between two adjacent values in a list is defined as the second
value minus the first value. For example, suppose a variable called "list" is an array of integers that stores the
following sequence of values.
(1, 3, 6, 7, 12)
The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (7 - 6) and the fourth gap is 5 (12 - 7).
Thus, the call:
minGap(list)
Should return 1 because that is the smallest gap in the list. Notice that the minimum gap could be a negative
number. For example, if list stores the following sequence of values:
(3, 5, 11, 4, 8)
The gaps would be computed as 2 (5 - 3), 6 (11 - 5), -7 (4 - 11), and 4 (8 -4). Of these values, -7 is the smallest,
so it would be returned. This gap information can be helpful for determining other properties of the list. For
example, if the minimum gap is greater than or equal to 0, then you know the list is in sorted (nondecreasing)
order. If the gap is greater than 0, then you know the list is both sorted and unique (strictly increasing).
If you are passed a list with fewer than 2 elements, you should return 0. Write your method in a class named
Gap.
Explanation / Answer
package arrayvalue;
public class MinimumGap {
public static void main(String[] args) {
int[] array = { 1, 3, 6, 7, 12};
for(int i=1;i<array.length; i++){
int gap = array[i] - array[i-1];
System.out.printf("Gap is : %d ( %d - %d ) = %d " ,i,array[i],array[i-1],gap);
}
}
public static void mingap() {
}
}
