for (let i = 0; i < len; i++) {
const result = Math.floor(nums[i])
}

for (let i = 0; i < len; i++) {
  const result = nums[i] | 0
}

 
for (let i = 0; i < len; i++) {  const result = nums[i] | 0}

for (let i = 0; i < len; i++) {
  const result = parseInt(nums[i])
}

 
for (let i = 0; i < len; i++) {  const result = parseInt(nums[i])}
