A full binary tree of height n has _________________ leaves. A. 2n B. 2n C. 3(n+1) D. 2(n+1) E. 3n

Which of the following is not a positional number system?*

First index of elementSend FeedbackTake an array with n elements with possibly duplicate elements as the input. The task is to find the index of the first occurrences of the element x in the array and, if it is not present, return -1.Input Format:The first line contains an integer N representing the size of the array.The next line contains N space-separated integers representing the elements of the array.The last line contains an integer 'x' whose index has to be found.Output Format:The only line of the output prints the Index or -1.Constraints:1 <= N <= 10^31 <= arr[i] <= 10^91 <= x < NSample Input 1 :87 5 2 11 2 43 1 12Sample Output 1 :2Explanation of Sample Input 1:2 is present twice in the input array and the first time it appears is at index 2.Sample Input 2 :87 5 2 11 2 43 1 110Sample Output 2 :-1Explanation of Sample Input 2:10 is not present in the array so the output is -1.

A(n) ________ is 8 bits.
