## How do you find the index of the maximum value in an array in Python?

To find the index of max value for a specific axis, specify the `axis` keyword argument in [`np.

argmax(a, axis=None)`](kite-sym:numpy.

argmax).

This returns a [`NumPy`](kite-sym:numpy) array with the indices of the max values of each row or column..

## What is the biggest number?

The biggest named number that we know is googolplex, ten to the googol power, or (10)^(10^100). That’s written as a one followed by googol zeroes.

## How do you find the second largest number without an array?

Originally Answered: Find second highest number without using array? let the array be int a[]=new int[n] with size n.

## How do you find the largest number in an array?

Java program to find largest number in an arrayInitialize array value.Step 2: (int max = a[0];) Initialize max value as array’s first value.Step 3: (for int i = 1; i < a.length; i++ ) ... Step 4: if(a[i] > max)Continue the loop and resign the max value if array current value is greater than max.Program. … Output.

## How do you count the number of elements in a 2d array?

Mark all elements using a hash table. Iterate in the array of numbers in the Z array, check if the number is present in the hash-table. Increase the count for every element present. Once all the elements are checked, print the count.

## How do you declare a 2d array in Java?

You can define a 2D array in Java as follows :int[][] multiples = new int[4][2]; // 2D integer array with 4 rows and 2 columns String[][] cities = new String[3][3]; // 2D String array with 3 rows and 3 columns.int[][] wrong = new int[][]; // not OK, you must specify 1st dimension int[][] right = new int[2][]; // OK.More items…

## How do I find the second largest number in Python?

Python Program to Find the Second Largest Number in a ListTake in the number of elements and store it in a variable.Take in the elements of the list one by one.Sort the list in ascending order.Print the second last element of the list.Exit.

## What is the length of a 2d array?

length to determine the number of rows in a 2D array because the length of a 2D array is equal to the number of rows it has. The number of columns may vary row to row, which is why the number of rows is used as the length of the 2D array.

## How do you find the index of a value in a list Python?

To find index of the first occurrence of an element in a given Python List, you can use index() method of List class with the element passed as argument. The index() method returns an integer that represents the index of first match of specified element in the List.

## How do you print the highest value in an array in Python?

ALGORITHM:STEP 1: Declare and initialize an array.STEP 2: Store first element in variable max.STEP 3: Loop through the array from 0 to length of the array and compare the value of max with elements of the array.STEP 4: If any element is greater than max, max will hold the value of that element.More items…

## What is a 2d array?

A 2D array has a type such as int[][] or String[][], with two pairs of square brackets. … The elements of a 2D array are arranged in rows and columns, and the new operator for 2D arrays specifies both the number of rows and the number of columns.

## How do you find the smallest number in an array?

#include

## How do you find the maximum and minimum of an array?

Below is the step by step descriptive logic to find maximum or minimum in array. Input size and element in array, store it in some variable say size and arr . Declare two variables max and min to store maximum and minimum. Assume first array element as maximum and minimum both, say max = arr[0] and min = arr[0] .

## How do you find the largest and smallest number without using an array?

If you are sure that your input will only be a positive number then you can initialize the largest with zero instead of Integer. MIN_VALUE. The program is simple, just take input from the user about how many numbers and then uses a for loop to get that many numbers as input by using Scanner. nextInt() method.

## How do you find the second largest number in an array without sorting?

Code below. int first=x[0]; int second=x[0]; x isn’t initialized yet. Prints -1 if no second largest element is found.

## How do you count the number of values in an array?

Answer: Use the PHP count() or sizeof() function You can simply use the PHP count() or sizeof() function to get the number of elements or values in an array. The count() and sizeof() function returns 0 for a variable that has been initialized with an empty array, but it may also return 0 for a variable that isn’t set.

## How do you find the largest value in a 2d array?

for(j=0;j

## How do you find the largest and second largest number in an array?

A simple way to find the largest and second-largest number is that sort the array in descending order and pick its first and second elements. Its first element will be the largest number and the second number will be the second-largest number. The time complexity of this solution is O(n log n).

## Can ArrayList be two dimensional?

Two-dimensional ArrayList In Java We know that an ArrayList does not have dimensions like Arrays. But we can have nested ArrayLists which are also called ‘2D ArrayLists’ or ‘ArrayList of ArrayLists’.

## What is a 3 dimensional array?

A 3D array is a multi-dimensional array(array of arrays). A 3D array is a collection of 2D arrays . It is specified by using three subscripts:Block size, row size and column size. More dimensions in an array means more data can be stored in that array.
