What's wrong in my code?
<
#include <stdio.h>
#include <string.h>

int main() {
        int i,h,w,n,tmp;
    int curLen = 0, curNumStr = 0;
    char s[105];
    scanf("%d%d%d\n",&h,&w,&n);
    for(i = 0; i < n; i ++) {
        gets(s); //scanf("%s",s);
        tmp = strlen(s);
        if(curLen)
            curLen += 1 + tmp;
        else
            curLen += tmp;
        if(curLen / w){
            curNumStr += curLen / w;

What's wrong with my code too?

h,w,n=map(int,input().split())
a=[]
for i in range(n):
    a.append(input())
lines=0
pag=0
while len(a)>0:
    if len(a)!=1:
        length=-1
        while length<w:
            length+=len(a[0])+1
            b=a[0]
            a.remove(a[0])
        if length>w:
            a.reverse()
            a.append(b)
            a.reverse()
        lines+=1
    else:
        lines+=1
        a.remove(a[0])

if lines%h==0:
    pag=lines//h
else:
    pag=lines//h+1
print(pag)

You are removing a[0], not element with index 0
So if there are several elements having the same value as a[0] they would be removed together with a[0]
So they would be not processed

Also I strongly recommend you not to store the entire input but process data just in time
