Find repeated elements in a having count

seems to work fine I have a having count, where I detect elements that repeat more than once. , Group by Product as well and it will work:
select MstDocCabId, count (*) as 'Repetition Number'
from skmov (nolock)
group by MstDocCabId, Product
having count(MstDocCabId) > 1

Find the highest repeated character in string and the count of the repeated character

Does that help Because the string may have more than a char have same most repeat count, so here is my solution:
- (NSArray *)mostCharInString:(NSString *)string count:(int *)count{
    NSMutableDictionary *dict = [NSMutableDictionary dictionary];
    int len = string.length;
    NSRange theRange = {0, 1};
    for (NSInteger i = 0; i < len; i++) {
        theRange.location = i;
        NSString *charStr = [string substringWithRange:theRange];
        int preCount = 0;
        if ([dict objectForKey:charStr]) {
            preCount = [[dict objectForKey:charStr] unsignedIntegerValue];
        }
        [dict setObject:@(preCount+1) forKey:charStr];
    }
    NSArray *sortValues = [[dict allValues] sortedArrayUsingSelector:@selector(compare:)];
    *count = [[sortValues lastObject] unsignedIntegerValue];
    return  [dict allKeysForObject:@(*count)];
}
int mostRepeatCount = 0;
NSArray *mostChars = nil;
mostChars = [self mostCharInString:@"aaabbbcccc" count:&mostRepeatCount];
NSLog(@"count:%d char:%@", mostRepeatCount, mostChars);
count:4 char:(
    c
)
mostChars = [self mostCharInString:@"aaabbbccccdddd" count:&mostRepeatCount];
count:4 char:(
    d,
    c
)

counting matching elements of two vectors but not including repeated elements in the count

fixed the issue. Will look into that further Use R's vectorization to your advantage here. There's no looping necessary.
You could use a table to look at the frequencies,
table(z[z %in% x])
# 
# 1 2 4 
# 2 1 1 
sum(table(z[z %in% x]))
# [1] 4

Python Program to Find count of repeated adjacent elements in array


Tag : python , By : browe

this will help Because you have alist[i+1] in for loop , you cant go through list until end , so you have to end it one element before end:
for i in range(len(alist)-1):
    if(alist[i] == alist[i+1]):
        counter+=2    # since you count both elements

alist=[1,2,2,3,3,5,6] # 4
alist=[4,5,6,6,8,8,8,8] # 8

Find repeated elements and it's count from multiple Flux's

will be helpful for those in need Since Map is a single item you can generate a Mono> as follows:
Mono<Map<String, Long>> result = Flux.merge(flux1, flux2).groupBy(it -> it).flatMap(group -> Mono.zip(Mono.just(group.key()), group.count())).collectMap(Tuple2::getT1, Tuple2::getT2);
Flux<Tuple2<String, Long>> result = Flux.merge(flux1, flux2).groupBy(it -> it).flatMap(group -> Mono.zip(Mono.just(group.key()), group.count()));
