Stack Basic CODING IN PYTHON

CODE:

stack=[]
stack.append("a")
stack.append("b")
stack.append("c")
print("Initial stack")
print(stack)
print(stack.pop())
print(stack.pop())
print(stack.pop())
print(stack)

OUTPUT:

Initial stack
['a', 'b', 'c']
c
b
a
[]

CODE:

from collections import deque
stack = deque()
stack.append("a")
stack.append("b")
stack.append("c")
print("intial stack")
print(stack)
print(stack.pop())
print(stack.pop())
print(stack.pop())
print(stack)


OUTPUT:

intial stack
deque(['a', 'b', 'c'])
c
b
a
deque([])

CODE:

from queue import LifoQueue
stack=LifoQueue(maxsize=3)
print(stack.qsize())
stack.put("a")
stack.put("b")
stack.put("c")
print("Full",stack.full())
print("Size",stack.qsize())
print(stack.get())
print(stack.get())
print(stack.get())
print("Empty",stack.empty())


OUTPUT:

0
Full True
Size 3
c
b
a
Empty True

Sort in specific order (GFG)

  Given an array   A   of positive integers. Your task is to sort them in such a way that the first part of the array contains odd numbers sorted in descending order, rest portion contains even numbers sorted in ascending order. Input: The first line of input contains an integer  T  denoting the number of test cases. Then  T  test cases follow. Each test case contains an integer  N  denoting the size of the array. The next line contains  N  space separated values of the array. Output: For each test case in a new line print the space separated values of the modified array. Constraints: 1 <= T <= 10 3 1 <= N <= 10 7 0 <= A i  <= 10 18 Example: Input: 2 7 1 2 3 5 4 7 10 7 0 4 5 3 7 2 1 Output: 7 5 3 1 2 4 10 7 5 3 1 0 2 4 Explanation: Testcase1:  Array elements 7 5 3 1 are odd and sorted in descending order, whereas 2 4 10 are even numbers and sorte...

Chef and Remissness Problem Code: REMISS (CodeChef)

Chef is now a corporate person. He has to attend office regularly. But chef does not want to go to office, rather he wants to stay home and discover different recipes and cook them. In the office where chef works, has two guards who count how many times a person enters into the office building.

But one better thing is that they never fall asleep at the same time. At least one of them remains awake and counts who enters into the office. Now boss of Chef wants to calculate how many times Chef has entered into the building. He asked to the guard and they give him two integers  A  and  B , count of first guard and second guard respectively. Help the boss to count the minimum and maximum number of times Chef could have entered into the office building. Input The first line of the input contains an integer  T ...
