Question

This is a python question, I need to remove elements that are strictly smaller than the other elements.

For example, 
temp = [[8,7],[5,5],[9,6],[10,5],[11,4],[12,3],[13,2],[8,8]]

[8,7] will be removed as it is strictly smaller than [8,8]

[5,5] will be removed as it is strictly smaller than [10,5] and [8,8]

Neither [13,2] nor [12,3] nor [11,4] nor [10,5] nor [9,6] nor [8,8] will be removed because they are not strictly smaller than each other.

Here is the completed code for this problem. Comments are included, go through it, learn how things work and let me know if you have any doubts or if you need anything to change. If you are satisfied with the solution, please rate the answer. Thanks

#code

temp = [[8,7],[5,5],[9,6],[10,5],[11,4],[12,3],[13,2],[8,8]]
#creating a list of elements that will be removed
toRemove=[]
#looping through each number pair in temp
for i in range(len(temp)):
    #storing the two numbers in x1 and y1
    x1,y1=temp[i]
    #looping through each and every other number pairs
    for j in range(len(temp)):
        #making sure that this element is not comparing to itself
        if i!=j:
            #storing current number pair in x2, y2
            x2,y2=temp[j]
            #checking if x1,y1 is strictly smaller than x2,y2
            if x1<=x2 and y1<=y2:
                #adding pair [x1,y1] to the toRemove list
                toRemove.append(temp[i])
              break #end of inner loop

#now we just loop through each element in toRemove
for i in toRemove:
    #and remove each value from temp
    temp.remove(i)

#now temp will contain the values [[9, 6], [10, 5], [11, 4], [12, 3], [13, 2], [8, 8]]
print(temp)

#output

[[9, 6], [10, 5], [11, 4], [12, 3], [13, 2], [8, 8]]
