Given a list of N integers, find the maximum and minimum element’s position in the list.
Input : 3, 4, 1, 3, 4, 5 Output : The maximum is at position 6 The minimum is at position 3
The naive approach will be to traverse in the list and keep track of the minimum and maximum along with their indices. We have to do N comparisons for minimum and at the same time N comparisons for maximum.
Below is the implementation of the naive approach.
Minimum Element in the list [8, 1, 7, 10, 5] is 1 Maximum Element in the list [8, 1, 7, 10, 5] is 10
Python inbuilt function allows us to find it in one line, we can find the minimum in the list using the min() function and then us index() function to find out the index of that minimum element. Similarly we can do the same for finding out the maximum element using max() function and then find out the index of the maximum element using index() inbuilt function in python.
Note : index() returns index of first occurrence in case there are multiple occurrences of an element. So if maximum (or minimum) occurs more than once, the first occurrence is returned.
Below is the implementation of the above approach:
The maximum is at position 6 The minimum is at position 3
