i dont mean to be so off topic but does anybody know of a trick to get back into an instagram account..? I was stupid lost the login password. I would appreciate any tips you can offer me

Nice video bro keep it up :D! An alternate solution: def sockMerchant(n, array): pairs = 0 set_of_array = set(array) for i in set_of_array: count = array.count(i) total_pair = count//2 pairs += total_pair return pairs

[@infinitygaming7192]

my solution def sockMerchant(n, ar): cat = Counter(ar) c = list(cat.values()) d = 0 for i in range(0,len(c)): if c[i] > 1: d += int(c[i]/2) return(d) i am working very hard i wish i become programmer like you

[@sachinsingh-jg9lx]

Wow nice solsn

[@prashnatdivase8523]

Alternate solution blank_list=[] count_of_pair=0 for i in ar: if i not in blank_list: cnt= ar.count(i) count_of_pair+= cnt//2 blank_list.append(i) return count_of_pair

[@prashnatdivase8523]

Can someone try and confirm?

My output keeps returning 2 instead of three and four for cases 1 and 2, what’s the reason for this?

[@codingcart]

Hahaaha ..Keep calm dude

[@Wonder_with_nature]

def pairlist(list): data = [] sum = 0 r = set(list) for i in r: res = list.count(i) data.append({i:res}) for j in data: for key, val in j.items(): result = val//2 sum = sum+result return sum

[@RohanVemula]

Can't we solve by solving with arrays Like arr[i]=arr[i+1]

[@codingcart]

Just give a try from your end 😊
