How do you find just greater elements in an array?

How do you find just greater elements in an array?

Step 1: Declare a stack and push the first array element into the stack. Step 2: Traverse the array and pick the array element one by one. Step 3: If the incoming array element is greater than the top element of the stack, then for the top element in the Stack, the incoming element is the next greater element.

How do I find the next largest permutation?

13 Answers

1. Find the highest index i such that s[i] < s[i+1] . If no such index exists, the permutation is the last permutation.
2. Find the highest index j > i such that s[j] > s[i] .
3. Swap s[i] with s[j] .
4. Reverse the order of all of the elements after index i till the last element.

Is there a smallest decimal that is greater than zero?

In mathematics there is no concept of smallest positive number. 1/ON is a concept larger than zero, but smaller than any positive number.

How do you clear a stack in C++?

stack empty() and stack size() in C++ STL. Stacks are a type of container adaptors with LIFO(Last In First Out) type of working, where a new element is added at one end and (top) an element is removed from that end only. empty() function is used to check if the stack container is empty or not.

How do you sort a stack without using any other data structure?

Sort a stack using a temporary stack

1. Create a temporary stack say tmpStack.
2. While input stack is NOT empty do this: Pop an element from input stack call it temp. while temporary stack is NOT empty and top of temporary stack is greater than temp,
3. The sorted numbers are in tmpStack.

Which of the following programming algorithms finds the first maximum element and then places it at the end?

The Selection Sort algorithm is based on the idea of finding the minimum or maximum element in an unsorted list and then putting it in its correct position in a sorted fashion.

What is lexicographically next greater permutation of numbers?

The lexicographically next permutation is basically the greater permutation. For example, the next of “ACB” will be “BAC”. In some cases, the lexicographically next permutation is not present, like “BBB” or “DCBA” etc. In C++ we can do it by using a library function called next_permutation().

How to find the next greater element in Excel?

For an array that is sorted in decreasing order, all elements have the next greater element as -1. For the input array [4, 5, 2, 25], the next greater elements for each element are as follows. d) For the input array [13, 7, 6, 12}, the next greater elements for each element are as follows.

Where is the next greater element in an array?

The Next greater Element for an element x is the first greater element on the right side of x in the array. Elements for which no greater element exist, consider the next greater element as -1. For an array, the rightmost element always has the next greater element as -1.

Which is the next greater element for element x?

The Next greater Element for an element x is the first greater element on the right side of x in array. Elements for which no greater element exist, consider next greater element as -1.

How to find the next greater element in nums2?

You are given two distinct 0-indexed integer arrays nums1 and nums2, where nums1 is a subset of nums2. For each 0 <= i < nums1.length, find the index j such that nums1 [i] == nums2 [j] and determine the next greater element of nums2 [j] in nums2. If there is no next greater element, then the answer for this query is -1.
