Given an integer N, the task is to find the minimum length string whose sum of each character (As a = 1, b = 2, … z = 26) equals to N.
Input: N = 5 Output: e 5 can be represented as "aac" or "ad" or "e" etc But we will take e as it is the minimum length Input: N = 34 Output: zj
- To minimise the length of the String, Greedy Approach will be used.
- By Greedy Approach, the solution will be very simple.
- The minimum length of the String will be
N/26 + 1 => if N % 26 != 0 N/26 => if N % 26 == 0
- And the minimum string can be found as
(N/26 times z) + (N%26) => if N % 26 != 0 (N/26 times z) => if N % 26 == 0
Below is the implementation of the above approach:
