## What is the index number of the last element of an array

Binary search: Binary search can also be used to find the index of the array element in an array. But the binary search can only be used if the array is sorted. Java provides us with an inbuilt function which can be found in the Arrays library of Java which will rreturn the index if the element is present, else it returns -1. The complexity

Given a sorted array of integers, find index of first or last occurrence of a given number. If the element is not found in the array, report that as well In normal binary search, we return as soon as we find any occurrence of the given target element in it. In order to find the first or last occurrence of an element Get the last element of an Array in JavaScript. 03 May 2016. #JavaScript. This article discusses the preferred way to retrieve the last element of an Array in JavaScript. Tip 7 in this Useful JavaScript Hacks Article proposes the following method to get the last item in an array. Get the last few elements in the array. What is the index number of the last element of an array with 9 elements? Explanation: Because the first element always starts at 0. So it is on 8 position. Searches for the specified object and returns the index of the last occurrence within the range of elements in the one-dimensional Array that contains the specified number of elements and ends at the specified index. LastIndexOf(T[], T) Searches for the specified object and returns the index of the last occurrence within the entire Array. Find missing element in a sorted array of consecutive numbers; Find index of an extra element present in one sorted array; Find element in a sorted array whose frequency is greater than or equal to n/2. k-th missing element in sorted array; Last duplicate element in a sorted array; Sum of minimum element of all subarrays of a sorted array Given a sorted array of integers, find index of first or last occurrence of a given number. If the element is not found in the array, report that as well In normal binary search, we return as soon as we find any occurrence of the given target element in it. In order to find the first or last occurrence of an element

## What is the index number of the last element of an array with 29 elements? A. 29. B. 28. C. 0. D. Programmer-defined 3. Which of the following is a two-

Binary search: Binary search can also be used to find the index of the array element in an array. But the binary search can only be used if the array is sorted. Java provides us with an inbuilt function which can be found in the Arrays library of Java which will rreturn the index if the element is present, else it returns -1. The complexity Element 2 is present at index 3 in the given array 3. std::find_if algorithm. Sometimes it is desired to search for an element which meets certain conditions in the array. For instance, find the index of first 2-digit number in the array. To handle such cases, the recommended approach is to use the std::find_if algorithm which accepts a predicate. The array has a Length property that will give you the length of the array. Since the array indices are zero-based, the last item will be at Length - 1. string[] items = GetAllItems(); string lastItem = items[items.Length - 1]; int arrayLength = array.Length; When declaring an array in C#, the number you give is the length of the array: Given a sorted array of integers, find index of first or last occurrence of a given number. If the element is not found in the array, report that as well In normal binary search, we return as soon as we find any occurrence of the given target element in it.

### Sets the array element at the specified index to the specified value. Returns a list containing all elements except last elements that satisfy the given predicate.

GetUpperBound() Method is used to find the index of the last element of the specified dimension in the array.. Syntax: public int GetUpperBound (int dimension); Here, dimension is a zero-based dimension of the array whose upper bound needs to be determined. Searches for the specified object and returns the index of the last occurrence within the range of elements in the one-dimensional Array that contains the specified number of elements and ends at the specified index. LastIndexOf(T[], T) Searches for the specified object and returns the index of the last occurrence within the entire Array. The positioning of array starts from subscript 0. Well subscript is also known as indices. It is the value in big brackets []. To find index number, u can use the formula (n-1). Here n=29 so (n-1)=28. Hence the index of the 29th element is 28. # Hope it helps. # Smritu. This method returns the index of the last occurrence of the specified element in this list. It will return '-1' if the list does not contain the element. Java program for how to get last index of arraylist. In this example, we are looking for last occurrence of string “alex” in the given list

### The index of the first occurrence of value , if it's found, within the range of elements in array that extends from startIndex to the last element; otherwise, the lower
