In a worksheet, there is a list of numbers which both have positive numbers and negative numbers, if you want to find the first or last positive or negative number in this column, how could you do?

To get the first positive or negative number in a list of data, the following formula may help you, please do as this:. If you need to find the last positive or negative number in a list of values, you can also apply array formula.

Follow Me. Below there is an Array of positive and negative number. Write a program that calculates how many of the numbers are positive and how many of them are negative. You are askig same Query. Hello, Sahni we know that in Header file we use less than and greater than symbol, But this page compile the whole page except page body that is why header files are not showing. So you will get email everytime we post something new here.

Logic:- For this problem simple fact you have to know that if the number is greater than zero then the number is positive if the number is less than the number is negative otherwise the number is zero.

So for this problem, we have two variable one for positive number and another for the negative number and as I said above we compare the number with zero or if the number is greater than zero we will increase the positive variable by one for negative increase negative variable by one.

The array can contain duplicates and negative numbers as well. This question was asked by Stripe in it's programming interview.

I have devised a solution for the same as below:. Here, I am first sorting the array, and then traversing the array once. Before traversing the array, I have initialized a variable named "min" as 1. Now, while traversing the array, when we get an integer that is equal to min, we simply increment the value of min. This ensures that the min variable hold the latest least positive integer that has not occurred yet. Can you think of any better approach?

Thanks in advance. We divide the array into 2 parts such that the first part consists of only positive numbers. Say we have the starting index as 0 and the ending index as end exclusive.

We traverse the array from index 0 to end. We take the absolute value of the element at that index - say the value is x. Finally, we traverse the array once more from index 0 to end.

This is the answer. However, if we do not encounter any positive element, it means that integers 1 to end occur in the array. In step 2 we change the signs of the positive numbers to keep track of which integers have already occurred. I think your approach works, but you should specify the type of sort you're doing so that it is clear it is a linear sort and not necessarily a full sort of the entire array.

This results in O N time without using any space. Scan the array, as you're scanning if the value in your current index is less than the length of the array then swap it with the value currently in that index.

Check Number is Positive Or Negative in C++ Programming

You must continue swapping until it no longer makes sense to swap at each index. Then at the end do one more scan until you find an index that isn't correct. Linear time. Here's a Python 3 implementation of pmcarpan's answer. Logic: If number is less than 0, it is rejected. Then the number is checked in dictionary if it exist, if yes, the next number is read else it is added to the dictionary. Dictionary in all will store all the number read in the list, plus any missing positive numbers in between the smallest number read in the list.

I didn't test it in detail, but for sorted array here is how I would approach it, any improvements are welcome. For each item in the array mark the index of the X, as 1 return the smallest index with 0.Given an array and a positive integer k, find the first negative integer for each window contiguous subarray of size k. If a window does not contain a negative integer, then print 0 for that window.

Naive Approach: Run two loops. In the outer loop, take all subarrays windows of size k. In the inner loop, get the first negative integer of the current subarray window. We create a Dequeue, Di of capacity k, that stores only useful elements of the current window of k elements. An element is useful if it is in the current window and it is a negative integer. We process all array elements one by one and maintain Di to contain useful elements of current window and these useful elements are all negative integers.

For a particular window, if Di is not empty then the element at front of the Di is the first negative integer for that window, else that window does not contain a negative integer. Optimized Approach: : It is also possible to accomplish this with constant space. The idea is to have a variable firstNegativeIndex to keep track of the first negative element in the k sized window.

Below is the solution based upon this approach. This article is contributed by Ayush Jauhari. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.

Python3 implementation to find the.Given an array of positive and negative numbers, arrange them such that all negative integers appear before all the positive integers in the array without using any additional data structure like hash table, arrays, etc. The order of appearance should be maintained.

A simple solution is to use another array. We copy all elements of original array to new array.

given an array of positive and negative numbers find the first ...

We then traverse the new array and copy all negative and positive elements back in original array one by one. This approach is discussed here. One approach that does not use any data structure is to use use partition process of QuickSort. The idea is to consider 0 as pivot and divide the array around it. The problem with this approach is that it changes relative order of elements.

The similar partition process is discussed here. We can modify insertion sort to solve this problem. Time complexity of above solution is O n 2 and auxiliary space is O 1. We have maintained the order of appearance and have not used any other data structure.

Approach 2: Optimized Merge Sort Merge method of standard merge sort algorithm can be modified to solve this problem. While merging two sorted halves say left and right, we need to merge in such a way that negative part of left and right sub-array is copied first followed by positive part of left and right sub-array. Time complexity of above solution is O n log n. We can do merging in-place without using any data-structure. The idea is taken from here.

Let Ln and Lp denotes the negative part and positive part of left sub-array respectively. Similarly, Rn and Rp denotes the negative and positive part of right sub-array respectively. Time complexity of above solution is O n log nO Log n space for recursive calls, and no additional data structure.
