pair of positive integers (a,b) is called uncommon if ⌊ab⌋=amodb. Here, ⌊ab⌋ is the aftereffect of the integer division among an and b, while amodb is its remaining portion.    You are given two integers x and y. Track down the number of uncommon sets (a,b) to such an extent that 1≤a≤x and 1≤b≤y.    Input    The main line contains a solitary integer t (1≤t≤100) — the number of experiments.    The main line of the depiction of each experiment contains two integers x, y (1≤x,y≤109).    Output    For each experiment print the appropriate response on a solitary line.
