Applies a ternary callback to elements in three five-dimensional nested input arrays and assigns results to elements in a five-dimensional nested output array.

## Notes

-   The function assumes that the input and output arrays have the same shape.

@param {ArrayLikeObject<Array<Array<Array<Array<Collection>>>>>} arrays - array-like object containing three input nested arrays and one output nested array
@param {NonNegativeIntegerArray} shape - array shape
@param {Callback} fcn - ternary callback
@returns {void}

@example
var add = require( '@stdlib/number/float64/base/add3' );
var ones5d = require( '@stdlib/array/base/ones5d' );
var zeros5d = require( '@stdlib/array/base/zeros5d' );

var shape = [ 1, 1, 1, 2, 2 ];

var x = ones5d( shape );
var y = ones5d( shape );
var z = ones5d( shape );
var out = zeros5d( shape );

ternary5d( [ x, y, z, out ], shape, add );

console.log( out );
// => [ [ [ [ [ 3.0, 3.0 ], [ 3.0, 3.0 ] ] ] ] ]
