Concatenate the Largest Digit Problem

You are given three non-zero numbers 'A', 'B', and 'C'. Your task is to determine the number created by concatenating the largest digit found in each number, in the sequence of 'A', 'B', and 'C'.

Example:

Input:

A = 5678, B = 45, C = 769

Output:

859

Explanation:

The largest digit in 'A' is '8', in 'B' is '5', and in 'C' is '9'. Concatenating these gives '859'.

Constraints:

1 ≤ T ≤ 10⁴

1 ≤ A, B, C ≤ 10⁶

Time limit: 1 Sec

Accepted Answer

Concatenate the largest digit from three numbers in sequence to form a new number.

Find the largest digit in each number 'A', 'B', and 'C'.
Concatenate the largest digits in the sequence 'A', 'B', and 'C' to form a new number.
Return the concatenated number as the output.
