Please help me in python You are given an array of integers. Your task is to create pairs of

them, such that every pair consists of equal numbers. Each array

element may belong to one pair only. Is it possible to use all of the

integers?

Write a function:

def solution$($A$)$

that, given an array A consisting of $N$ integers, returns whether it is

possible to split all integers into pairs.

Examples:

Given $A=[1,2,2,1],$ your function should return True, as the

pairs are $($A$[0],$ A$[3])($both have value $1)$ and $($A$[1],$ A$[2])($both have

value $2).$

Given $A=[7,7,7],$ your function should return False, as you can

make one pair of numbers $7,$ but you still have a single $7$ left.

Given $A=[1,2,2,3],$ your function should return False, as there's

nothing that $A[0]$ can be paired with.

Write an efficient algorithm for the following assumptions:

$N$ is an integer within the range $[1.\mathrm{.}100,000]$;

each element of array $A$ is an integer within the range

$-1,000,000.\mathrm{.}1,000,000.$
