But trust me, once you understand how hard it is to get good intraday data, you won't think this is very much money at all.

How do malloc() and free() work?

... virtual memory manager can handle (most often multiples of 512 bytes e.g. 4KB). So returning 40 Bytes to the OS will just not work. So what does free do?

O(nlogn) Algorithm - Find three evenly spaced ones within binary string

...airs would be of the order of the square of the number of 1s in it: that's 4k ≈ n1.26 which unfortunately is asymptotically much larger than (n log n). In fact, the worst case is even worse: Leo Moser in 1953 constructed (effectively) such strings which have n1-c/√(log n) 1s in them but no evenl...
