PRACTICE PROBLEMS
1) Given an arrayArrof sizeN, print secondlargest distinct
element from an array.
Example 1:
Input:
N = 6
Arr[] = {12, 35, 1, 10, 34, 1}
Output: 34
Explanation: The largest element of the
array is 35 and the second largest element
is 34.
2) Given an arrayArrofNpositive integers. Your task is to
find the elements whose value is equal to that of its index
value (Consider 1-based indexing ).
Note: There can be more than one element in the array which
have the same value as its index. You need to include every such
element's index.Follows 1-basedindexing of the array.
Example 1:
Input:
N = 5
Arr[] = {15, 2, 45, 12, 7}
Output: 2
Explanation: Only Arr[2] = 2 exists here.
3) For a given3digit number, find whether it is armstrong
number or not.AnArmstrong numberof three digits is an
