283 Move Zeroes 1

Joel Castillo Espinosa 2

DESCRIPTION

Given an integer array nums, move all 0’s to the end of it while maintaining the relative order of the non-zero elements.

Note that you must do this in-place without making a copy of the array.

Examples

  • Example 1:
    • Input: nums = [0,1,0,3,12]
    • Output: [1,3,12,0,0]
  • Example 2:
    • Input: nums = [0]
    • Output: nums = [0]

Constraints:

  • 1 ≤ nums.length ≤ $10^4$
  • $-2^{31}$ ≤ nums[i] ≤ $2^{31}$ - 1

SOLUTION 3

zeroes <- function(nums){
  # vectors: zeroes and non zeroes
  nums1 <- nums[nums != 0]
  nums0 <- nums[nums == 0]
  
  # add in the final vector
  return(c(nums1, nums0))
}

Examples using the function

We can use the examples presented before.

zeroes(c(0,1,0,3,12))

## [1]  1  3 12  0  0

zeroes(c(0))

## [1] 0
