Count Total Positives, Negatives, and Zeros from an Array
Count Total Positives, Negatives, and Zeros from an Array
Description:
Given an array arr[] of integers, write a program to count the number of positive, negative, and zero numbers present in the array.
Example 1:
Input: arr = {1, -2, 3, 0, -5}
Output: Positive: 2, Negative: 2, Zero: 1
Explanation: There are 2 positive numbers (1, 3), 2 negative numbers (-2, -5), and 1 zero (0) in the array.
Example 2:
Input: arr = {0, 0, 0, 0, 0}
Output: Positive: 0, Negative: 0, Zero: 5
Explanation: All elements in the array are zero.
Constraints:
The array length |arr| is at least 1 and at most 10^5.
Java Code:
public class HackerAlgo {
// Count Total Positives, Negatives, and Zeros
public static void countPositivesNegativesZeros(int[] arr) {
int positiveCount = 0;
int negativeCount = 0;
int zeroCount = 0;
for (int num : arr) {
if (num> 0) {
positiveCount++;
} else if (num< 0) {
negativeCount++;
} else {
zeroCount++;
}
}
System.out.println("Positive: " + positiveCount + ", Negative: " + negativeCount + ", Zero: " + zeroCount);
}
public static void main(String[] args) {
// Example for Count Total Positives, Negatives, and Zeros
int[] arr1 = {1, -2, 3, 0, -5};
countPositivesNegativesZeros(arr1);
int[] arr2 = {0, 0, 0, 0, 0};
countPositivesNegativesZeros(arr2Python Code:
# Count Total Positives, Negatives, and Zeros
def count_positives_negatives_zeros(arr):
positive_count = sum(1 for num in arr if num> 0)
negative_count = sum(1 for num in arr if num< 0)
zero_count = len(arr) - positive_count - negative_count
print(f"Positive: {positive_count}, Negative: {negative_count}, Zero: {zero_count}")
# Example usage
arr1 = [1, -2, 3, 0, -5]
count_positives_negatives_zeros(arr1)
arr2 = [0, 0, 0, 0, 0]
