Question

Write a program to find previous and next number of a given no​

Answer 1

Answer:

Input : arr[] = {2, 3, 1, 5, 4, 9, 8, 7, 5}

Output : 3, 5, 9

In above given example 3 is greater than its

left element 2 and right element 1.

Similar logic is applied to other elements

hence our final output is 3, 5, 9.

Input : arr[] = {1, 2, 3, 2, 1}

Output : 3
