A simple solution is to use two loops….Method 2 (Efficient: O(n Log n)
- Sort array in ascending order. This step takes O(n Log n) time.
- Initialize difference as infinite. This step takes O(1) time.
- Compare all adjacent pairs in sorted array and keep track of minimum difference. This step takes O(n) time.
How do you find the absolute minimum difference?
For an element x present at index i in the array its minimum absolute difference is calculated as: Min absolute difference (x) = min(abs(x – arr[j])), where 1 <= j <= n and j != i and abs is the absolute value.
What is a maximum difference?
Maximum difference between two elements such that larger element appears after the smaller number in C. The task is to find the maximum difference between two elements such that the larger element appears after the smaller number. That is Arr[j]-Arr[i] is maximum such that j>i.
How do you find the difference between two elements in an array?
Method 1 (Simple) Use two loops. In the outer loop, pick elements one by one and in the inner loop calculate the difference of the picked element with every other element in the array and compare the difference with the maximum difference calculated so far. Below is the implementation of the above approach : C++
What is Peak element?
The peak element is an element that is greater than its neighbors. Suppose we have an input array nums, where nums[i] ≠ nums[i+1], search for a peak element and return its index. The array can hold multiple peak elements, in that case return the index to any one of the peak elements.
How do you find the sum of a stack?
“sum of stack c++” Code Answer
- stack si;
- int sum = 0;
- stack tsi(si);
- while (! tsi. empty()) {
- sum += tsi. top();
- tsi. pop();
- }
How do you calculate absolute difference in Java?
abs(int a) returns the absolute value of an int value. If the argument is not negative, the argument is returned. If the argument is negative, the negation of the argument is returned.
How do you find the greatest difference?
You only have the digits 1,2,3,4,5 so the largest 3 digit number that you can make is 543 and the smallest 2 digit number you can make is 12. Thus the largest possible difference you can make is between 543 and 12 that is 543 – 12 = 531.
How do you find the max element in an array?
To find the largest element from the array, a simple way is to arrange the elements in ascending order. After sorting, the first element will represent the smallest element, the next element will be the second smallest, and going on, the last element will be the largest element of the array.
How do you find the largest and smallest number in C?
Iterative program to find the smallest and largest elements in an array
- / C program to find the smallest and largest element in an array.
- int main() {
- printf(“\nEnter the number of elements : “); scanf(“%d”,&n);
- printf(“\nInput the array elements : “);
- scanf(“%d”,&a[i]);
- large=small=a[0];
- for(i=1;i
- large=a[i];
How do you find the maximum and minimum of an array?
The function getresult( int arr[],int n) is to find the maximum and minimum element present in the array in minimum no. of comparisons. If there is only one element then we will initialize the variables max and min with arr[0] . For more than one element, we will initialize max with arr[1] and min with arr[0].
