Solve Inequalities to find boundary for one variable

36 Views Asked by At

X<0 and Y<0 : as we are having sorted array and we are picking two pairs.

arr: -7, -3 ,3, 4, 7

so I can have number in this way (-7, -3), (-3, -7) <--- this won't be the case as I am having order. so (X<Y)
hence min(|X|, |Y|) = |Y|

|X-Y|<= min(|X|, |Y|)

|X-Y| <= |Y|

now how to solve to get range for Y in terms of X to get its boundary which holds true.

I have two conditions to satisfy

min(|x-y|,|x+y|)<=min(|x|,|y|)
max(|x-y|,|x+y|)>=max(|x|,|y|)

so designing the cases. Currently stuck at x<0 and y<0
