((Array.isArray(a) && (typeof a[0] === 'string') && ((a[1] == null) || (typeof a[1] === 'number')))) &&
(((!!b && (typeof b === 'object') && !Array.isArray(b)) && Object.keys(b).every(function(k){return ((typeof k === 'string') && (typeof b[k] === 'number'));}))) &&
(((typeof c === 'string') || (typeof c === 'number')))
