Answer / sunil

if a, b and c are the three sides of a triangle, then a + b > c
if this is not satisfied, then its not a valid triangle.

To check for right angle, use Pythagoras theorem. Assume
that the longest side is the hypotenuse.

Issosless and Equilateral can be found by simply comparing
the sides.

Answer / giri

One should check for valid sides also. Side values dhould
be greated than ZERO.

Here is the correct routine:
public static String checkTriangle(int[]
triangleSide){
boolean validTriangle = false;
boolean validSides = true;
String result = "NOT VALID TRIANGLE";

for(int side: triangleSide)
if(side <= 0)
validSides = false;

if(validSides){
for(int count= 0; count< 3 ;
count++){
if(((triangleSide[count%3]
+ triangleSide[(count+1)%3]) > triangleSide[(count+2)%3]))
validTriangle =
true;
}

if(validTriangle){
if( triangleSide[0] ==
triangleSide[1] && triangleSide[2] == triangleSide[1])
result
= "EQUILATERAL";
else{
for(int count= 0;
count< 3 ; count++){

if( (
triangleSide[count%3] * triangleSide[count%3] + triangleSide
[(count+1)%3] * triangleSide[(count+1)%3]) == (triangleSide
[(count+2)%3] * triangleSide[(count+2)%3])){

result = "RIGHANGLED";

break;
}else
if
((triangleSide[count%3] == triangleSide[(count+1)%3]))

result = "ISOSCALAUS";
}
}
if("NOT VALID
TRIANGLE".equals(result))
result = "NOT
SPECIAL";

}
}

System.out.println(result);
return result;
}

Answer / ganesh bhat

I believe, this is more efficient one. solves all the cases.. comments please. Written in java

public static Map validateTriange(int a,int b,int c)
{
Map props = new HashMap();
boolean isValidTriangle;

int bigSide = a;
if(bigSide<b){bigSide = b;}
if(bigSide<c){bigSide = c;}

boolean isSpecial = false;

if((a+b+c-bigSide)>bigSide)
{
props.put("VALID","YES");
}
else
{
props.put("VALID","NO");
return props;
}

if(a == b||b==c||c == a)
{
props.put("ISOSCELES","YES");
isSpecial = true;
}

if(a == b && b == c)
{
props.put("EQUALATERAL","YES");
isSpecial = true;
}


if(((a*a+b*b+c*c)-bigSide*bigSide) == bigSide*bigSide)
{
props.put("RIGHT_ANGLED","YES");
isSpecial = true;
}

return props;
}

why rownum=1 works properly but not rownum=>2,=>3 etc.
