太折磨了这个

#include<bits/stdc++.h>
using namespace std;
int main() {
	int n,a[3]= {0,0,0},b=0,c=0,ba=0,bb=0,bc=0;
	char m;
	cin>>n;
	for(int i=1; i<=n; i++) {
		cin>>m;
		if(m=='a'||m=='A') {
			a[0]++;
			ba++;
		} else if(m=='b'||m=='B') {
			a[1]++;
			bb++;
		} else if(m=='c'||m=='C') {
			a[2]++;
			bc++;
		}
	}
	sort(a,a+3);
	for(int i=2; i>=0; i--) {
		if(a[i]==ba) {
			cout<<'a'<<" "<<a[i]<<endl;
			ba+=9999;
		}
		if(a[i]==bb) {
			cout<<'b'<<" "<<a[i]<<endl;
			bb+=9999;
		}

有点难

奈何看不懂C++

s = input()
s = s[:num].lower()
a, b, c = 0, 0, 0
for n in s:
    if n == "a":
        a += 1
    elif n == "b":
        b += 1
    elif n == "c":
        c += 1
t = [("a", a), ("b", b), ("c", c)]
def c_sort(m):
    return (-m[1], m[0])
t.sort(key=c_sort)
for v in t:
    print(v[0], v[1])
