Easy
A DNA string is a sequence composed of the symbols 'A', 'C', 'G', and 'T'. Given a DNA string, your task is to count how many times each nucleotide appears in the string. You should write a code on your PC, run it with the provided input, and then paste your results here and click on submit.
Sample Input:
AGCTTCGA
Sample Output:
A: 2, C: 2, G: 2, T: 2
Constraints:
The DNA string will contain at most 1,000,000 nucleotides.
Explanation:
In the sample input, the DNA string "AGCTTCGA" contains:
- 2 occurrences of 'A'
- 2 occurrences of 'C'
- 2 occurrences of 'G'
- 2 occurrences of 'T'
Your task is to count the occurrences of each nucleotide and print them in the format shown in the sample output.
