I Love T code chef solution in C

Read sentences until user enters 0
for each sentence, if the first character in each word in the given sentence is vowel, append T and if it is not vowel replace that character by T. 
Also only first character in each word only must be capital letter.

Sample Input:
love apples
apples are gOOOd for HelatHH
0

Sample Output:
Tove Tapples
Tapples Tare Toood Tor Telathh



#include<stdio.h>
int isvowel(char ch)
{
    if(ch >='A' && ch <= 'Z')
        ch=ch+32;
    if(ch == 'a' ||ch == 'e'||ch == 'i'||ch == 'o'||ch == 'u')
        return 1;
    else
        return 0;
}

int main()
{
    char st[1000001];
    scanf("\n%[^\n]\n",st);
    while(st[0] != '0')
    {
        int i;
        for(i=0;st[i]!='\0';i++)
        {
        if(st[i] >= 'A' && st[i] <= 'Z')
                st[i]=st[i]+32;
        if(i == 0|| (st[i-1] == ' ' && st[i] != ' '))
        {
         
            if(isvowel(st[i]))
                printf("T%c",st[i]);
            else
                printf("T");
        }
        else
            printf("%c",st[i]);
        }
        printf("\n");
        scanf("\n%[^\n]\n",st);
    }
    return 0;

Resize an image keeping Aspect Ratio using Python

import cv2
import numpy as np

img = cv2.imread('flower.jpg');
# To resize the image keeping aspect ratio
rows=100.0/img.shape[1] #img.shape[1] gives the number of rows
dimensions = (100, int(img.shape[0]*rows))
resized = cv2.resize(img, dimensions, interpolation = cv2.INTER_AREA)
cv2.imshow("Original", img)
cv2.imshow("Resized", resized)
cv2.waitKey(0)
cv2.destroyAllWindows


Output:

Add the integral and decimal part of a floating number without using . in scanf in C

#include<stdio.h>
int main()
{
    float x=12.25;
    int y=x,c=0;
    float d = x-y;
 
    for(; x !=((int)x);x = x*10)
    {
        c++;
    }
    while(c>0)
    {
        d=d*10;
        c--;
    }
    printf("%d",y+(int)d);

Questions on Conditional Statements in C:


Library fine:
https://www.hackerrank.com/challenges/library-fine/problem

#include<stdio.h>
int main()
{
int dr,mr,yr,de,me,ye,fine=0;
scanf("%d%d%d",&dr,&mr,&yr);
scanf("%d%d%d",&de,&me,&ye);
if(yr == ye)
{
if(mr > me)
fine =(mr-me)*500;
else if(mr == me)
{
if(dr>de)
fine = (dr-de)*15;
}
}
else if(yr>ye)
fine =10000;
printf("%d",fine);
return 0;
}


Given an integer, , perform the following conditional actions:
  • If  is odd, print Weird
  • If  is even and in the inclusive range of  to , print Not Weird
  • If  is even and in the inclusive range of  to , print Weird
  • If  is even and greater than , print Not Weird
The above statements can be converted to 

 if the number is from 6 to 20 and the number is odd then  print "Weird" and if the number is even also print "Weird" and so we conclude if the number is even or odd and is from 6 to 20 then print "Weird"
so the condition becomes

if( n %2 != 0 || (n>=6 && n<= 20))
                   printf("Weird");
else
                  printf("Not Weird");
