The SPLICE function returns a dynamic array of the element by element concatenation of two dynamic arrays.
SPLICE(array1, expression, array2)
Each element of array1 is concatenated with expression and with the corresponding element of array2.
The result is returned in the corresponding element of a new dynamic array. If an element of one dynamic array has no corresponding element in the other dynamic array, the element is returned properly concatenated with expression. If either element of a corresponding pair is null, null is returned for that element. If expression evaluates to null, null is returned for the entire dynamic array.
PRINT SPLICE (A,C,B)
The output of this program is:
