Interview Questions (3)
Given an array of positive integers, return the absolute difference between alpha and beta of the array.
Alpha : No of times an element 'k' appears exactly 'k' consecutive times.
Beta : No of times an element 'k' appears exactly 'k' consecutive times starting at index k. (1-based indexing)
example:
input: arr=[2,2,2,4,4,4,4,3,3,3,2,2]
output: 2 (|3-1|)
Aplha - 3 (3 instances - 4,3,2)
Beta - 1 (only one instance - element 4 appears 4 times consecutively starting at index 4).
Given an array of whole numbers, Find the lowest whole number which is not present in the list of the whole numbers obtained by performing the bitwise OR operation on all of the subsequences of the array.
example:
input: [1,3,4,0]
output: 2
[0] => 0
[4] => 4
[4, 0] => 4
[3] => 3
[3, 0] => 3
[3, 4] => 7
[3, 4, 0] => 7
[1] => 1
[1, 0] => 1
[1, 4] => 5
[1, 4, 0] => 5
[1, 3] => 3
[1, 3, 0] => 3
[1, 3, 4] => 7
[1, 3, 4, 0] => 7
2 is the smallest whole number which is not present in the result set.
Given n jars with capacity of [c1,c2....cn] liters, and each jar containing intial water of [i1,i2....in] liters, Find the minimum no of transfers required to measure 'X' liters of water.
constraints:
2<= n <=4
(output) min no of transfers required <= 6
