JoinArrays method

The JoinArrays function takes the leftArr and rightArr integer arrays as parameters. The combined array is returned in the following code:

// Join Arrays methodfunc JoinArrays(leftArr []int, rightArr []int) []int {  var num int  var i int  var j int  num, i, j = len(leftArr)+len(rightArr), 0, 0  var array []int  array = make([]int, num, num)  var k int  for k = 0; k < num; k++ {    if i > len(leftArr)-1 && j <= len(rightArr)-1 {      array[k] = rightArr[j]      j++    } else if j > len(rightArr)-1 && i <= len(leftArr)-1 {      array[k] = leftArr[i]      i++    } else if leftArr[i] < rightArr[j] {      array[k] = leftArr[i]      i++    } else {      array[k] = rightArr[j]      j++    }  }  return array}
