Remove repeated digits in a given number

 Remove repeated digits in a given number 

Given an integer N, remove consecutive repeated digits from it.

Input:
The first line of input contains an integer T denoting the number of test cases. Then T test cases follow. The first line of each test case contains the integer N.

Output:
Print the number after removing consecutive digits. Print the answer for each test case in a new line.


Constraints:
1<= T <=100
1<= N <=1018


Example:

Input:
1
12224

Output:
124


Solution:

t=int(input())

for i in range (t):

    stack =[]

    number = input()

    for i in number:

        if len(stack)>0:

            if stack[-1] != i:

                stack.append(i)

        else:

            stack.append(i)

    print("".join(stack))

Short Note of Data Structure

  Arrays   An array is collection of items stored at continuous memory locations. The idea is to declare multiple items of same type together.  Array declaration:  In C, we can declare an array by specifying its and size or by initializing it or by both. // Array declaration by specifying size int arr[10]; // Array declaration by initializing elements int arr[] = {10, 20, 30, 40}; // Array declaration by specifying size and // initializing elements int arr[6] = {10, 20, 30, 40} Formulas:    Length of Array = UB - LB + 1 Given the address of first element, address of any other element is calculated using the formula:- Loc (arr [k]) = base (arr) + w * k w = number of bytes per storage location of for one element k = index of array whose address we want to calculate Elements of two-dimensional arrays ( mXn ) are stored in two ways:- Column major order: Elements are stored column by column, i.e. all elements of first column are stored, and then all elements of

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 sorted in ascending order. SOLUTION: t=int(input()) for i in range (t):     n=int(input())     p=list(map(int,input().split()))
