Python program to print sorted number formed by merging all elements in array
Given an array arr[], the task is to combine all the elements in the array sequentially and sort the digits of this number in ascending order.
Note: Ignore leading zeros.
Examples:
Input: arr =[7, 845, 69, 60]
Output: 4566789
Explanation: The number formed by combining all the elements is “78456960” after sorting the digits we get 4566789
Input: arr =[8, 5603, 109, 53209]
Output: 1233556899
Explanation: The number formed by combining all the elements is “8560310953209” after sorting the digits we get “1233556899”
Approach:
- Convert each element of the list to a string using map() function.
- Join the list using join() function.
- Sort the string using join() and sorted()
- Convert string to an integer using type casting
- Return the result
Below is the implementation of the above approach:
Python3
# python program to print sorted number by merging # all the elements in array function to print # sorted number def getSortedNumber(number): # sorting the string number = ''.join(sorted(number)) # converting string to integer number = int(number) # returning the result print(number) # function to merge elements in array def mergeArray(lis): # convert the elements of list to string lis = list(map(str, lis)) # converting list to string string = ''.join(lis) # passing this string to sortednumber function getSortedNumber(string) # Driver code lis = [7, 845, 69, 60] # passing list to merge array function to merge # the elements mergeArray(lis) |
Output:
4566789
