Count occurrences

Given an array arr[] and an integer target, find the number of occurrences of target in the array. The implementation scans every element, so the input does not need to be sorted.

Hint

Start at the beginning of the list. Check each item in the list. If the current item matches the "target" value, add 1 to the count.

# Python implementation

ls = [1, 2, 3, 4, 3, 3, 3, 8, 9]
target = 3
count = 0

for item in ls:
  if item == target:
    count += 1

print(count)

// Javascript implementation

const list = [1, 2, 3, 4, 3, 3, 3, 8, 9];
const target = 3;

let output = 0;

for (let item of list) {
  if (item == target) {
    output++;
  }
}

console.log(output);
