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

No need to sort, just iterate through the array, keeping track of the largest value seen so far and the index of that value. var largest = -1; var player = -1; for (var i = 0; i < allPlayers. Length; ++i) { if (allPlayers[i] > largest) { player = i; largest = allPlayers[i]; } } Console.

How do I find the second largest number in an array in Excel?

Strategy: Use the LARGE or SMALL functions. These functions take a range of values, then a k value. If you use a k value of 1, the LARGE function is exactly like a MAX: =LARGE(B2:B100,1). The real value in LARGE is the ability to ask for the second largest value using =LARGE(B2:B100,2).

How do you find two maximum numbers in an array?


  1. Take two variables; let’s call them first and second and mark them as -∞.
  2. Iterate through the array and for each element (let’s call it current), Compare it with the first and if first is less, assign the first value to second and assign current to first.

How do you remove duplicates from an array?

Remove duplicates from sorted array

  1. Create an auxiliary array temp[] to store unique elements.
  2. Traverse input array and one by one copy unique elements of arr[] to temp[]. Also keep track of count of unique elements. Let this count be j.
  3. Copy j elements from temp[] to arr[] and return j.

How do you find the smallest integer in an array?

For an array of ascending order the first element is the smallest element, you can get it by arr[0] (0 based indexing). If the array is sorted in descending order then the last element is the smallest element,you can get it by arr[sizeOfArray-1].

How do you determine if a number is even or odd in Java?

Now, to check whether num is even or odd, we calculate its remainder using % operator and check if it is divisible by 2 or not. For this, we use if…else statement in Java. If num is divisible by 2 , we print num is even. Else, we print num is odd.
