string? e = words.Find(e => e.StartsWith("w")); Here, the predicate is a lambda expression that checks if a word begins with 'w'. $ dotnet run war 3 C# List FindLastThe FindLast method returns the last element i
To avoid this, it is important to use the right method to find the element you are trying to act on. Finding an element using an index can help to avoid tests that produce inconsistent results. In this Selenium Python tutorial, we will discuss how to find index of element in list with...
try: index = my_list.index(search_element) except ValueError: index = None print(index) # 2In this example, we used the index() method of lists to find the index of the first occurrence of the search element in the list. This method returns the index of the element if it is found...
Could not found the element 32 in vector Alternatively, we may use thestd::findalgorithm that’s part of the STL library. This function returns the iterator to the first element that satisfies the condition. On the other hand, if no element is found, the algorithm returns the last element...
We can easily find the index of a specific list element using theindexOf()method. You can follow the below example code with an explanation for this purpose. Example Code: // importing necessary packagesimportjava.util.List;publicclassFindIndex{publicstaticvoidmain(String[]args){// Creating a...

binarySearch(array, element); if (index >= 0) { return index; } else { return -1; // Element not found } } public static void main(String[] args) { int[] array = {1, 2, 3, 4, 5}; int element = 3; int index = findIndexApproach2(array, element); System.out.println("...
