* Takes elements from one of two strided arrays depending on a condition.

* @param {PositiveInteger} N - number of indexed elements
* @param {Collection} condition - condition array
* @param {integer} strideC - stride length for `condition`
* @param {Collection} x - first input array
* @param {integer} strideX - stride length for `x`
