Hello Programmers, In this post, you will learn how to solve HackerRank Pangrams Solution. This problem is a part of the HackerRank Algorithms Series.
One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions. We are going to solve the HackerRank Algorithms problems using C, CPP, JAVA, PYTHON, JavaScript & SCALA Programming Languages.
HackerRank Pangrams Solution
Task
A pangram is a string that contains every letter of the alphabet. Given a sentence determine whether it is a pangram in the English alphabet. Ignore case. Return either pangram or not pangram as appropriate.
Example
s = ”The quick brown fox jumps over the lazy dog”
The string contains all letters in the English alphabet, so return pangram.
Function Description
Complete the function pangrams in the editor below. It should return the string pangram if the input string is a pangram. Otherwise, it should return not pangram.
pangrams has the following parameter(s):
- string s: a string to test
Returns
- string: either
pangramornot pangram
Input Format
A single line with string s.
Constraints
- 0 < length of s <= 103
- Each character of s, s[i] ∈ {a – z, A – Z, space}
Sample Input 0
We promptly judged antique ivory buckles for the next prize
Sample Output 0
pangram
Explanation 0
All of the letters of the alphabet are present in the string.
Sample Input 1
We promptly judged antique ivory buckles for the prize
Sample Output 1
not pangram
Explanation 1
The string lacks an x
