Python program to construct Equidigit tuples

Given the Elements list, divide the tuple list into similar digit tuples pairs.

Input : test_list = [5654, 223, 982143, 34, 1021] 
Output : [(56, 54), (2, 23), (982, 143), (3, 4), (10, 21)] 
Explanation : Element in tuples equidistributed.

Input : test_list = [5654, 223, 1021] 
Output : [(56, 54), (2, 23), (10, 21)] 
Explanation : Element in tuples equidistributed. 

Method #1 : Using loop + slicing + str()

In this, we perform the task of dividing by getting mid-idx and then slice from mid, initially integral number is split to a string by using str().

Python3

# Python3 code to demonstrate working of
# Construct Equidigit tuples
# Using loop + slicing str()

# initializing list
test_list = [5654, 223, 982143, 34, 1021]

# printing original list
print("The original list is : " + str(test_list))

res = []
for sub in test_list:

    # getting mid element
    mid_idx = len(str(sub)) // 2

    # slicing Equidigits
    el1 = str(sub)[:mid_idx]
    el2 = str(sub)[mid_idx:]

    res.append((int(el1), int(el2)))

# printing result
print("Equidigit tuples List : " + str(res))

Output:

The original list is : [5654, 223, 982143, 34, 1021] Equidigit tuples List : [(56, 54), (2, 23), (982, 143), (3, 4), (10, 21)]

Time Complexity: O(n)
Auxiliary Space: O(n)
