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:
- Sum of the alphabetical values of the characters of a string
- Minimum length of the sub-string whose characters can be used to form a palindrome of length K
- Remove all non-alphabetical characters of a String in Java
- Check if the characters of a given string are in alphabetical order
- Average of ASCII values of characters of a given string
- Count characters in a string whose ASCII values are prime
- Minimum length substring with exactly K distinct characters
- Program to find the product of ASCII values of characters in a string
- Minimum operations to make frequency of all characters equal K
- Minimum deletions from string to reduce it to string with at most 2 unique characters
- Program to check if first and the last characters of string are equal
- Print common characters of two Strings in alphabetical order
- Maximum length of balanced string after swapping and removal of characters
- Length of the smallest sub-string consisting of maximum distinct characters
- Character whose frequency is equal to the sum of frequencies of other characters of the given string
