You have been given an integer 'N'. Find the nearest multiple of 10 to the given integer 'N'.

Note:

If there are multiple answers, find the smallest one. For example, if N = 35, both 30 and 40 are nearest to N, since 30 is smaller, the expected answer will be 30.

Ninja has been given a binary string ‘STR’ containing either ‘0’ or ‘1’. A binary string is called beautiful if it contains alternating 0s and 1s.

For Example:‘0101’, ‘1010’, ‘101’, ‘010’ are beautiful strings.

He wants to make ‘STR’ beautiful by performing some operations on it. In one operation, Ninja can convert ‘0’ into ‘1’ or vice versa.

Your task is to determine the minimum number of operations Ninja should perform to make ‘STR’ beautiful.

For Example :

Minimum operations to make ‘STR’ ‘0010’ beautiful is ‘1’. In one operation, we can convert ‘0’ at index ‘0’ (0-based indexing) to ‘1’. The ‘STR’ now becomes ‘1010’ which is a beautiful string. 

You have two strings “A” and “B”. Your task is to print these two strings in an alternative fashion according to indices i.e. first character of “A”, the first character of “B”, the second character of “A”, the second character of “B” and so on.

Note:

If all characters of one string are printed and some characters of other string are remaining, then you have to print the remaining characters of the other string at the end of the resulting string.

Can you solve the problem in O(N) time complexity and O(1) space complexity?

For Example:

A = “abc” B = “fdh” then answer will be afbdch.

You are given an array consisting of 'N' distinct positive integers and a number 'K'. Your task is to find the kth largest element in the array.

Example:

Consider the array {2,1,5,6,3,8} and 'K' = 3, the sorted array will be {8, 6, 5, 3, 2, 1}, and the 3rd largest element will be 5.

Note:

1) Kth largest element in an array is the kth element of the array when sorted in non-increasing order. 

2) All the elements of the array are pairwise distinct.
